You may have noticed that the capacity of Music Hall of Williamsburg isn't quite on par with their recent gigs at Lollapalooza and All Points West this summer or Radio City last week, so it might be tough to get your paws on a ticket. But when you see Karen O, wearing who in the hell knows what, accepting her Academy Award for soundtracking Where the Wild Things Are, you'll look back on tonight with warm, warm, memories. Plus, they're one of New York's last-standing, performance-based rock bands, so there's that too.
