On 19 January, Brit band The Heavy was on Letterman. They blew the roof off; normally staid Letterman was so excited that he told them to "go again! go again!", and so they did.
Don't miss this. For SRS. It's James Brown meets hip-hop meets R&B meets, I dunno, the growl and smash of Zeppelin. TOP NOTCH, as a friend of mine used to say.
(Via MeFi, which also links the official video. MeFi also points out why you know this song already. Them kids is goin' places.)
Thanks for posting this. That series of commercials make my laugh my ass off every single time, but I hadn't gotten around to looking up the music yet.
