MGMT have an important message for fans: MORE COWBELL!!!

As you may recall, the Brooklyn-based indie band performed "Your Life Is a Lie," from their self-titled third album, on Letterman with a massive cowbell, struck by frontman Andrew VanWyngarden with a baseball bat-sized drum stick. Awesome. Well, Andrew needs help on MGMT's upcoming tour—and you can be the band's designated cowbell player! See, dreams do come true.

MGMT posted a clip on Instagram explaining the competition (watch below). One winner will be picked to play "Your Life Is a Lie" onstage with MGMT in each city on the band's 14-date East Coast tour. To enter, follow @WhoIsMGMT on Instagram. Next, upload a video of yourself playing the cowbell along to any MGMT song. Use the hashtags #BiggerCowbell and #MGMTYOURCITY (ex: #MGMTLouisville). "Be as creative as you can," the band encourage.

Check out the full instagram video below, then watch the zany music video for "Your Life Is a Lie" for inspiration. And Will Ferrell and Christopher Walken's original Saturday Night Live skit is always worth re-watching.
