To celebrate twenty years of providing a home to some of the most seminal underground music in history, Sub Pop Records is throwing a party. Taking place on July 12 and 13th in their native Seattle, the label will gather former and present acts for the SP20 Festival. Leading the charge are old school favorites Mudhoney, the Fluid and a reunion of Green River (which features members of Pearl Jam, Mudhoney and Love Battery) and new schoolers Wolf Parade, Iron & Wine, Flight of the Conchords and No Age. The label will also host a comedy festival featuring Patton Oswalt, Eugene Mirman and Todd Barry. Sub Pop also plans on reissuing some of their greatest hits, with Mudhoney’s Superfuzz Bigmuff the first to get the deluxe treatment. To see the initial batch of artists playing SP20, follow the jump.
