Watch MGMT Play Letterman

MGMT took their great LP3 single “Your Life Is A Lie” to the Late Show last night. Dialing down the wackiness of the video just a bit, Andrew Van Wyngarden was dressed like a hipster Captain Caveman and lackadaisically smacked a giant cowbell throughout the performance. It was pretty amusing, but many on Twitter were not impressed. Watch the performance below.

MGMT is out 9/17 on Columbia.
