Atmospheric-rock band Slowdive play a sold-out CMJ Music Marathon show at Terminal 5 on Saturday night. And even if you don’t already have tickets, you still might be able to go because The House List is giving away two of them. Want them to be yours? Then try to Grow a Pair. It’s easy. Just fill out the form below, making sure to include your name, full e-mail address, which show you’re trying to win tickets to (Slowdive, 10/25) and a brief message explaining which band you’re most excited to see at CMJ (other than this UK five-piece). Eddie Bruiser, a music-festival lover, will notify the winner by Friday.
