Rocking stages in his trademark LED mouse helmet, Joel Zimmerman recalls the salad days of Daft Punk, when cartoon robots ruled clubland. 4x4=12 is audacious, mixing generic house grooves with eclectic fare like "Bad Selection," a kinetic jam with dog-whistle synth builds. The masterstroke is "Raise Your Weapon," which breaks down into a sick dubstep beat. "How does it feel now, to watch it burn?" asks singer Greta Svabo Bech before the bass hits. So what's burning? Your synapses, dude.
