the SubGround.

SubGround Collective is a Phoenix-based underground electronic music and event-production company — throwing real, high-production shows in spaces the city doesn't know about until the doors open.

Bass, underground, and frontline electronic music staged inside warehouses and industrial rooms: concert-grade sound, projection-mapped walls, laser design, and multi-camera film crews — all produced in-house. Immersive, psychedelic, and mysterious by design.

Founded by Ryan Sanfilippo. Powered by a roster of 20+ artists who know exactly what this is.

The Prescott Woods

Northern Arizona · Forest rave · 2 stages

A two-stage rave deep in the pines — a full step out of the warehouse and into the trees. Taking shape now; details drop when they’re locked.

TBA

Dream Fest

The long game · 3 stages · scaling 5,000 → 10,000

The horizon: a full three-stage festival built on everything above. The reason all of this exists.

Flagship SIGNAL 001 — the crowd lit blue at the secret warehouse
Past Event · IfYouKYK.
SIGNAL
001
May 16, 2026 Secret Location 21+ 21 Artists

Our flagship. Twenty-one artists across one secret warehouse, ~450 people, and a night the city didn't know about — until it did.

SIGNAL 001 turned a party into a movement: a standing residency offer from the venue, new relationships with promoters and DJs, and a brand people now recognize on sight. This is the bar. 002 raises it.

Press play.

The roster

Built in-house

The production

One team, end to end. We don't rent a vibe — we build it, from the sound rig to the final cut.

Concert-Grade Sound

Funktion-One-style rigs tuned for the room — physical, full-range bass that you feel before you hear it.

Projection Mapping

Custom Resolume visuals mapped across walls and surfaces — turning raw rooms into living, psychedelic canvases.

Laser & Lighting

Blue, violet and green beam design cut through the haze — atmosphere engineered frame by frame.

Multi-Cam Film

Full film crews capturing every set — content that lets the night live on and sells the next one.

Immersive Staging

Secret locations, considered layouts, and staging that pulls people all the way inside the experience.

End-to-End

Booking, artists, build, sound, visuals, security, capture — one collective handling the whole show.
