Watch MGMT Perform “Your Life Is A Lie” on Letterman

MGMT were on The Late Show With David Letterman last night, performing “Your Life Is A Lie,” which is set to appear on their forthcoming third album, out September 17. The band turned in a somewhat lacklustre, seemingly abbreviated performance on the song, but on the plus side, showed off the biggest cowbell you’ll see this week. Watch the performance above.
