A single CD of short edits is an odd thing for a prog-techno act who specialize in spacious songs that often run for more than 10 minutes. The live "Cowgirl" is nothing and the dubstep moves are clumsy. No matter: Motormouth vocalist Karl Hyde and music man Rick Smith (plus, in the Nineties, Darren Emerson) headline festivals because they craft hooks, however abstruse at times. An R&B star should sample the surging synths of "Two Months Off" and "Dark and Long." The creeping menace of "Rez" hasn't abated a bit. And "Born Slippy (Nuxx)" is one of the strangest generation-defining anthems ever recorded.
