I · The offerings

Six crafts, one circle

I

Audio

90,000+ watts of systems, consoles, and microphones — engineered and mixed by the owners, tuned to the space.

II

Video

Projection mapping, LED walls, screens, streaming and cameras — moving image woven into the space.

III

Lighting

36+ moving heads, 40+ uplights, washes and market lights — programmed looks that breathe with the music.

IV

Lasers

Four 2-watt full-color units under full control with custom designs — geometry drawn in light above the crowd.

V

Planning & Design

Theme, decor and scenery design, graphics and editing — the vision shaped long before the first case rolls in.

VI

Performance

DJs and producers from the collective's own circle — the gathering's sound can arrive with its makers.

From the field

Lasers over the tents, consoles in the cave shows, builds in progress — the record lives on Instagram until this page carries it.
