For decades, the world of live music has largely been categorized into neat, genre-specific boxes—rock, electronic, jazz, funk, and so on. Some prefer more niche subgenres like vaporwave, acid house, doom jazz, glitch hop, or sludge metal. But defining a subgenre is like trying to nail jelly to a wall: no matter how hard you try to pin it down, it keeps slipping and changing shape. Just when you think you have it figured out, new influences and sounds stretch and reshape it in ways you didn’t expect. Few styles have morphed and defied rigid classifications quite like the contemporary convergence of live improvisation in jam bands and electronic dance music. What once seemed like distinct musical traditions—for example, Phish’s expansive, improvisational rock or Pretty Lights’ sample-heavy, beat-driven solo productions—have now found themselves intertwined in ways that challenge traditional genre boundaries.
A Brief History: From Psychedelia to the Dance Floor
From Jazz to Jam
The roots of jam bands stretch back to the 1960s. The Grateful Dead pioneered and mastered the freeform, improvisational ethos that would later define acts like Phish, Widespread Panic, and The String Cheese Incident. Jam bands built their reputation on spontaneity, lengthy instrumental explorations, and live performances that often veered into uncharted sonic territories.
The improvisational spirit of jam bands owes much to the traditions of jazz, a genre that has long emphasized spontaneous creativity and dynamic performance. Much like jazz musicians, jam bands embrace the freedom to explore musical ideas in the moment. They often veer off into unknown territory – and typically that territory is where the magic happens. Influential jazz figures such as Miles Davis and John Coltrane set the stage for this kind of experimentation. They encouraged musicians to take risks and push boundaries. Jam bands, following in this legacy, prioritize live improvisation over rehearsed material. They make each performance take on a uniquely arcane shape. This emphasis on improvisation allows jam bands to connect with their audiences in a deeply personal way. Each performance is a new chronological milestone where the music unfolds in real-time, fueled by the energy of the crowd and driven by the band’s chemistry.
Where the Beat Started
On the other hand, EDM emerged primarily from club culture. It was shaped by disco, house, and techno pioneers like Kraftwerk, Giorgio Moroder, and the Detroit techno scene. In its early stages, EDM was heavily reliant on prerecorded music and multitrack controllers. Producers used synthesizers, drum machines, and sequencers to create intricate, layered beats; traditional instruments like guitars, drums, or horns were largely absent. The genre focused on electronic sounds and rhythms generated from hardware and software. DJs would manipulate these pre-recorded tracks live, adjusting tempos, adding effects, and creating transitions between songs. But the improvisation was vastly different than that of a jam band.
This reliance on studio production and electronic equipment allowed for precision and consistency but limited traditional improvisation or live instrumentation. Over time, as live DJing became more prevalent as a performance art, the boundaries between the roles of producer and performer started to blur. As artists began experimenting with live manipulation of their sounds, a more dynamic, improvisational approach was the natural next step.
While early electronic music was often highly structured and reliant on studio production, the advent of live DJing and electronic improvisation essentially erased the lines between producer and performer. By the late 1990s and early 2000s, acts like The Disco Biscuits and STS9 began merging the spirit of jam with the sounds and technology of EDM. The earliest pioneers used live instrumentation while incorporating electronic production techniques. This fusion created a hybrid genre that defied classification and pushed boundaries further and further over time.
The Vanguard of Modern Jamtronica
A standout example of this genre-blending expression is Pretty Lights, spearheaded by Derek Vincent Smith. For years Smith performed solo with original music that was electronic in nature but impossible to categorize in any predetermined genre. Often mistaken as just a DJ, he was always a relentless innovator pushing the boundaries of live production. He did so with live drums, synths, and his famous monome (an early DIY production controller that allowed him to trigger samples in real-time). Even at the start, his shows were far more than just a DJ set. They were live, immersive performances that invited listeners into a new realm of sound manipulation, and it built up a cult-like following fast.
Analog Future
As Pretty Lights grew, so did the complexity of his live shows as he began tagging in new talent and testing new iterations of a live band. The first major shift came with Analog Future, a version of the band that introduced drums, horns, and an almost overwhelming array of analog synthesizers. This configuration allowed the band to explore new musical terrain, incorporating more spontaneous, improvised jams that pushed the boundaries of the electro-soul genre Smith had pioneered. The result was a more organic, layered performance that felt more like a jam session than a tightly scripted show.
Pretty Lights Live
From there, the setup evolved into Pretty Lights Live, which removed the horns and refined the band’s soundscape into new uncharted territories with every improvisation or “flip” as they were called. The new iteration turned the sound into something even more experimental and unpredictable, unleashing a new wave of energy and creativity.
I will personally never forget the first time I ever cried from a music performance witnessing that band iteration’s debut. Smith had been stepping it up performance after performance and it seemed like the band couldn’t possibly get any better. But they did. I bawled because I was so proud of where they were able to take the sound. They achieved the ability to play electro hip-hop as a fully improvised jam. I was aghast at the infinite possibilities that unfolded in my mind as the eight minute Color of My Soul opener seemed to almost stop and transform into something unheard of. “They did it…” I recall exclaiming to myself. They carved out a nebulous blossom of new possibilities for a genre – no, an art form that didn’t exist before.
The Swirlbridge of the Soundship Spacesystem
Following a five year hiatus, Smith debuted an entirely new and radically futuristic concept for the live band. We fondly refer to the newest setup as the Swirlbridge, an allusion to the cockpit or bridge of a next-gen spaceship that brought the jams to new heights. Instead of “flips,” the band’s improvisations became “swirls” – a term the band and fanbase dub in for nearly infinite uses. The Soundship Spacesystem tour further fused vintage samples with artful hip-hop beats and masterful live instrumentation. Long extended improvisation sessions began to define the multi-night runs. Often no clear song from the discography appeared to be the underlying sonic canvas. Fans were forced to ask, “Is Pretty Lights officially a jam band now?”
It is hard to deny. The way Smith incorporated live musicianship into his performances, as well as his exploration of more spontaneous, free-form jams, suggests that Pretty Lights is indeed threading the needle between the worlds of jam bands and EDM. A project that had largely gained fame as a solo electro-soul producer, has now evolved into something undefined. Pretty Lights is connecting the jam and electronic worlds. The incontrovertible evidence was when Pretty Lights played songs by Phish, the Grateful Dead, and many more on tour. Paying tribute directly to the forefathers of jam bands cemented the idea that in this hybrid space, anything is possible. The band has also given nods to the traditions of jazz and jam with sit-ins from other artists. Most notably on the recent two tours, they have brought out Tipper, Dominic Lalli, and the Shady Horns.
The New Unknown
Pretty Lights recently teased a new name or iteration: Pretty Lights – Horizon Sprinter & The Prismatic Fleet. Could it be a different band configuration or just another mysterious play on words? It’s hard to say, but whispers indicate that the new “fleet” will allow for the members to have more autonomy and even more opportunities to jam and perform solos. This may appear similar to the band’s performance on Night 2 of Boston at Roadrunner where they decidely experimented with different band connections. No doubt, Electric Hawk will be reporting on whatever they roll out next.
When The Jam Bands Get Wubby
If Pretty Lights is the perfect example of an EDM artist delving into jam, then taking a look at another cult-like collective would suggest that Phish is a jam band that has pushed the limits of electronic sound. Phish, widely known for their improvisational live performances and jam-band ethos, has, over the years, incorporated electronic elements into their music in ways that can sometimes be construed as EDM. Though they’re rooted in rock, funk, and jazz traditions, their exploration of electronic textures and effects during live performances blurs the line between jam bands and electronic music.
Synthesizers and Effects
Phish’s use of synthesizers, particularly from keyboardist Page McConnell, has been a defining feature of their sound. In certain songs, the synthesizer lines evoke the kind of futuristic, spacey sounds that are often associated with electronic music. During their live shows, Phish often uses various effects and looping technologies. This creates a soundscape that is much more electronic in nature, rather than the long traditional jam band vibe of guitars and bass.
Live Sampling and Looping
Their experimentation with looping and sampling, especially in the late 1990s and early 2000s, also brings them closer to EDM territory. They’ve used live looping pedals to build intricate patterns on stage, layering sounds in real-time—a technique that parallels live electronic performances. The repetition of motifs, the gradual building of rhythms, and the reliance on electronic processing during performances (often using devices like the “SuperCollider”) all mirror the production techniques seen in modern EDM.
“Spacey” Jams
Phish’s extended improvisations—sometimes referred to as “space jams,” also take on a distinctly electronic character at times. These jams often incorporate ambient and minimalistic elements as well. They can resemble the sound design and experimentalism you might hear in genres like IDM (Intelligent Dance Music) or downtempo electronic music. The electronic-inspired aspects of these jams become even more pronounced when they employ synthesizers to generate unusual sounds and textures, veering away from the traditional rock feel.
Dance Grooves
While Phish is not often considered a “dance band” in the same way EDM artists are, some of their grooves and basslines lean toward danceable rhythms that wouldn’t sound out of place at an EDM festival. Tracks like “Sand” and “Twist” incorporate funky, syncopated basslines and rhythmic motifs that echo the types of grooves that underpin house or techno music. These tracks often make use of repetitive loops and build-ups that are characteristic of EDM. They utilize long, drawn-out progressions leading to peaks in energy and emotion that resemble the climaxes of dance music.
Electronic-Influenced Tracks
Over the years, Phish members have also collaborated with electronic musicians, further bridging the gap between their sound and EDM. For instance, Trey Anastasio, the lead guitarist, has been known to experiment with electronic-based side projects and collaborations. A notable example is his work with STS9, another act known for their fusion of jam and electronic sounds. STS9 has also notably shared stages with Pretty Lights as well.
Collaborations
While Phish is primarily known for their jam-band style, their use of electronic elements—synthesizers, effects, live sampling, and danceable rhythms—gives their music an electronic edge that overlaps with aspects of EDM. Their improvisational style allows them to seamlessly integrate these influences into their performances, making it possible for listeners to draw parallels between the live energy of Phish shows and the spirit of modern EDM festivals.
What Defines Jam Bands and EDM?
While jam bands and EDM producers approach music differently, they often utilize similar technology to achieve their signature sounds.
- Looping and Sampling: Jam bands rely on loop pedals (such as the Boss RC-300 or the Line 6 DL4) to build layers of sound in real time, much like an electronic artist sequencing beats in Ableton Live.
- Synthesizers and Effects: Phish’s Page McConnell and STS9’s David Phipps employ analog and digital synths to create expansive textures, while many electronic producers often use software synths (Serum, Massive) and drum machines to craft beats.
- Improvisational Tech: Both genres rely on spontaneity. While jam bands lean on instrumental musicianship, electronic artists have traditionally used live controllers (like Ableton Push or Native Instruments Maschine) to manipulate beats and samples on the fly. This art dates further back, however, to spinning and scratching vinyl.
- Light Shows and Production: Both styles emphasize the live experience, with immersive visual elements enhancing the music. Acts like Pretty Lights and STS9 have pioneered synchronized lighting rigs that stand up next to even the most elaborate Phish or Dead productions – No easy feat.
Theoretically: Where the Genres Overlap
Despite their different origins, jam bands and EDM share surprising similarities in musical structure:
- Modal Improvisation: Jam bands often use modes (such as Mixolydian or Dorian) for extended jams, similar to how electronic producers build tension with harmonic layering.
- Repetitive Grooves and Builds: Much like a DJ layering loops before a drop, jam bands use cyclical grooves and gradual tension-building to engage audiences.
- Polyrhythms and Syncopation: STS9, for example, incorporates complex rhythmic structures reminiscent of house and techno beats, making their music dancefloor-friendly despite being played by a live band.
The Modern Blurring of Lines
The 2020s have seen the lines between jam and EDM dissolve even further. Acts like Sunsquabi and The Floozies seamlessly blend live funk instrumentation with electronic production, while festival lineups now place jam bands and EDM headliners side by side. Phish’s influence can even be seen in electronic acts who embrace improvisation, such as STS9’s dynamic sound design or Pretty Lights’ extended live jams.
As music continues to evolve, the overlap between jam bands and EDM proves that genre lines are meant to be crossed. While Phish and Pretty Lights may come from different traditions, they share a common ethos: music as a living, breathing, ever-evolving force. Whether it’s through guitars or MIDI controllers, one thing is clear—the jam and EDM worlds are more connected than ever, and the future looks bright for those who thrive in the in-between spaces.
Conclusion
Perhaps the greatest takeaway is that both genres emphasize the experience—whether it’s a 30-minute jam or a meticulously crafted DJ set. Both worlds prioritize spontaneity, crowd interaction, and a sense of collective euphoria that transcends genre labels. And of course, both are rooted in community. The reason that the most prominent artists in either genre (or perhaps the pioneers of the space between) are so beloved is because of the fanbases they have built – crazed, enthusiastic fanbases that will hyper-analyze their music enough to write articles like this one. So, whether you call it jam or electronic or just good music, just keep on dancing and spreading love for the music community.
