MGMT put a different spin on "more cowbell" last night on the Late Show With David Letterman, where Andrew Van Wyngarden thunked intermittently on an oversized version bearing the slogan "Be Aware" throughout the group's performance of "Your Life Is a Lie." The rest of the six-piece band churned along behind him, stopping and starting proficiently on the song from the group's upcoming album MGMT, which is due out Sept. 17.
