Ace four-tracker. Caves was created in the aftermath of a devastating set by DJ Stingray, and sounds like it: storming but funky, infused with the spirit of classic Detroit techno. Spacetown marries Arpanet and John Carpenter, with a saturnine melody which sticks in the mind. Flip it for a deadly Caves remix by man-of-the-year Convextion, inimitably sci-fi but banging; and the elemental, ambient accomplishment of The Strips, consolidating the promise on show throughout.
