Concerts are okay, I guess. Everyone dances a bit, shoves around and watches a group of about four or five people play their instruments, drunk. Oh my god, it's been so done. But at Les Savy Fav's performance at the McCarren Park JellyNYC Pool Party this Sunday, there was dodgeball, a slip 'n' slide, and a pasty fat man lead singer who really has no business showing off any skin below his neck changing outfits and bringing hula hoopers up on stage. Pay attention, New York. This is the future of music. Next week: Dead Meadow,The Slip, Mobius Band, and Psychic Ills.Photos by Jon Bahr
