Kevin Barnes’s genre-spanning Of Montreal bring their wild live show to a sold-out Music Hall of Williamsburg tomorrow night. But we’re not telling you that to brag. No, The House List is actually giving away two tickets. So if you don’t already have any but would still like to go, try to Grow a Pair of tickets for F-R-E-E. It’s easy. Just fill out the form below, making sure to include your full name, e-mail address, which show you’re trying to win tickets to (Of Montreal, 5/22) and a brief message explaining your Memorial Day weekend plans. Eddie Bruiser, who’s looking for a worthwhile way to spend his three-day weekend, will notify the winner tomorrow. Good luck.
