The Juan MacLean are kind of a secret weapon for DFA Records—low profile, but responsible for killer dance 12-inches like the muscular "Give Me Every Little Thing" and this year's delirious house revival "Happy House." As a live band, the Juan MacLean dish out a floor-shaking mix of live and programmed percussion, synths, effects, and vocals (with LCD Soundsystem's Nancy Whang). MacLean may not have an "All My Friends" under his belt, but he does have an agogo (it's like a cowbell) tucked into his pants, and he's not afraid to use it.
