Kraftwerk Berlin was opened as a performance venue in 2006, in the old Mitte CHP Plant, a power station built in East Berlin in the early 1960s and abandoned in 1997. On a recent Saturday evening, as the time crept towards midnight, I lay on a canvas camp bed in the middle of the turbine hall listening to Alvin Lucier perform his pioneering piece of sound art, I am sitting in a room.
