PARK SLOPE Peter Bjorn and John, whose new album Gimme Some, out 3/29, harkens back to Writer’s Block and its melodic, infectious pop rock, are playing a late-night show at The Rock Shop. (Have a listen to their newest single here.) Tickets went lickety split, but we have one pair for a random winner who emails us by tomorrow at 9am (we’ll announce the winner here then). P.S. Follow @tigermountainbk and you’ll get wind of other secret, late-breaking shows like PB&J.
