Yesterday Cage The Elephant's new album Thank You, Happy Birthday was released and to coincide with this, the band paid a visit to David Letterman's late night slot and brought along a few performance. Up at the top you can check their performance of the single "Shake Me Down", which also got the official video treatment yesterday. After the jump you can watch an online exclusive performance of "Around My Head". Liking the sound these guys have got on the new album. Looks like they have some nice pedal boards too. Kudos. Thanks to our friends over at The Audio Perv for the videos.
