02 · THE HALLS

Four halls, one building

PUMP HALL

CAP 1,100

The original engine floor. Six-metre ceiling, no seating, and a reverb tail nobody has managed to tame since 1971.

FILTER HOUSE

CAP 600

Twelve dry filter beds with the gravel removed. Quadraphonic. Standing on the bed walls is permitted and, frankly, the point.

OUTFALL

CAP 450

Open air, under the discharge arches. Runs until sunrise on Friday and Saturday. Bring a coat — it is eleven degrees down there in July.

The fourth is SLUDGE LANE, capacity 250, in the old dosing corridor. It is not on the map and it does not have a schedule.

05 · PRACTICALITIES

Before you ask

+There is no headliner on the bill. Is that a mistake?

No. Every act is listed by set time only. The Sunday closer plays all four halls at once through a shared feed, which is the closest thing to a headline slot we run.

+Can I bring a camera?

Handheld, yes. No detachable lenses over 55 mm, no tripods, no drones. The halls are dark and the flash will make you unpopular.

+What is actually still in the building?

Most of it. The pumps, the gantry crane, the filter beds and the chlorine contact tanks are all in place and structurally surveyed. The water is not.

+Is it loud?

Yes. 103 dB(A) averaged in Pump Hall. Free plugs at every bar, and the Outfall stage sits twelve decibels below the indoor halls if you need a night off.
