Animal Collective @ Bowery Ballroom (more by J Caldwell)
As someone pointed out, Animal Collective is one of the artists playing the Celebrate Brooklyn series of concerts at the Prospect Park Bandshell in Brooklyn this summer. It's not a free show though. $30 tickets for the August 14th show go on sale Wednesday at noon, but are on "venue presale" NOW (password?).
TV on the Radio, M Ward and others are playing shows in Central Park this summer.
Animal Collective is also playing Terminal 5 in May, and many other places.
