To call these guys simply a "rock band" would be woefully leaving out a large chunk of their musical stew. Disco, soul, funk, and a large dose of the Purple One all figure into the sound. Still, it rocks. And though they broke up for a minute a couple of years ago, it didn't last long, and ever since then, they've been stepping up their game, touring and appearing at industry requisite events such as CMJ and South by Southwest. Around here, though, the band remains one of the most universally loved live acts, creating an instant dance party within the first few bars. Here's further proof they're in tune with the cultural Zeitgeist: Not only did they put their recent full-length, Rational Geographic Vol. 1, up for free download on their website, but also they somehow got Blair Waldorf herself — Gossip Girl's Leighton Meester — to record a cover of their song "Birthday." For real. OMG!
