01 FEB 2025 / Leamington Spa
Mayhem × ETB × Nazca
Mayhem, Nazca and ETB joined two rooms and two soundsystems for six hours of tekno, hard techno, jungletek, jungle and 4×4 pressure.
Fresh from Secret Garden, Mayhem returned with something much larger: Kelsey's rooftop and basement handed over to three crews, two systems and two distinct rooms moving at once.
The point was to pull Leamington and the wider West Midlands rave scenes into the same building. Tekno, hard techno, jungletek, jungle and 4×4 moved between floors without forcing the night into one musical lane.
As always, Mayhem was a safe and inclusive space. Anyone feeling uncomfortable or unwell could speak to the crew or venue staff and be looked after.

THE PEOPLE IN THE ROOMS
CREWS +
ARTISTS
ETB Crew
Extra Terrestrial Bass / Gloucestershire
A Gloucestershire soundsystem collective built around bass music with an intergalactic streak. Their residents move through hard-hitting club sounds with enough weight to make the rooftop feel temporarily detached from Earth.
Nazca Sound System
Midlands
A Midlands collective whose identity draws on the mystery of the Nazca Lines and Peruvian visual culture. Psytrance, tribal rhythm, progressive movement and acid techno are treated as one continuous journey rather than separate genres.
1step
ETB Crew
Leamington-raised and Manchester-based, 1step came from garage and bassline into a first techno set: sharp mixing, hardgroove momentum and a dose of schranz with no gentle introduction.
Jago Vialan
ETB Crew
A newer name with a direct approach: raw pressure, hard kicks and restless transitions designed to make the system work for its place in the room.
0wrld
ETB Crew
A reset of the underground palette through distorted energy, boundary-crossing selections and a set shaped to feel like the beginning of something rather than a finished formula.
Maximize
ETB Crew / Nazca
A Leamington force in drum & bass and jungle. Maximize brought speed and high-impact movement to a bill otherwise rooted in harder four-to-the-floor forms — the outlier that widened the night.
Muzo
Nazca
Long, high-energy passages of techno and psytrance that move through distinct phases without losing the floor. Hypnotic, driving and central to the Nazca sound.
Anarchist
Nazca
Nazca's harder edge: hardcore pressure, acid squelch and dark, repetitive rhythms that keep building after the obvious peak should have passed.
Sleepless
Nazca
The bridge inside the collective — deep bass and layered synths connecting tribal psychedelia to acid and harder rave forms, with intensity added one layer at a time.
Fab
Nazca / Leamington Spa
Born and raised in Leamington, Fab pushes Nazca's tribal rhythm furthest into industrial territory: physical percussion, machine texture and a distinctly local sense of pressure.
