Swingin' on the Flippity-Flop: Sub Pop Turns 20

The snotty love child of Seattle-based music geeks Bruce Pavitt and Jonathan Poneman, and home of Iron & Wine, Hot Hot Heat, The Shins, The Postal Service and The Helio Sequence--not to mention ground zero for Nirvana, Soundgarden and Mudhoney, of course--will leave adolescence behind on April 1st of this year. A series of anniversary shows with past and present roster acts--including a rumored Green River reunion--are in the works.
