Now that we're knee-deep into summer, it's time to recap the big festivals going on this season. Coachella and Bonnaroo have come and gone, so now our eyes are on, among others, Lollapalooza in Chicago, Outside Lands in San Francisco, and Rock the Bells in cities nationwide. And it's not too late to catch the Sub Pop 20th Anniversary Festival. This two-day tribute to one of the greatest indie labels ever is happening in Seattle--aka the home of grunge rock--this weekend. Road trip!
