Shaggy hipster heads explode as indie rockers the Cold War Kids play with Elvis Perkins and Sam Champion, and the best news is, we’ve heard of at least one of these people! This concert is part of an outdoor festival, Celebrate Brooklyn! (Haven’t we been doing that for five years straight now?) Best part of all this, hipsters? It’s sponsored by Starbucks, where you’re all going to end up as barristas once you discover the family trust fund has already been spent by Uncle Floyd…
