Raime, Demdike Stare and Blackest Ever Black congregate for a seventh time, to play vinyl records, loudly. You can expect to hear the kind of sounds that inform their own releases, but beyond that there's no policy, no programme, no promises. This is a night for 120 people who want to hear independent and idiosyncratic music from all quarters and all eras, in a basement with a bar... with the added bonus of the bank holiday Easter Friday.
