Sohn kicks off his U.S. tour with two shows at Music Hall of Williamsburg on Thursday and Friday. They’re both sold out but The House List is giving away two tickets to see him on Halloween. And if you want them to be yours, try to Grow a Pair. 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 (Sohn, 10/31) and a brief message explaining your favorite thing about Halloween. Eddie Bruiser, who likes lots of things about Halloween, will notify the winner by Friday. Good luck.
