I first heard this at World Unknown in that arch club in Loughborough Junction - they had a massive wall of speakers on one end (I think it was a soundsystem designed for dub IIRC), DJs on the other and a dark dank dancefloor in between, with no lights but a seizure-inducing strobe, and the overuse of a smoke machine. The bass on it is extraordinary, impressive even on my weedy Bluetooth speaker
