This week we were pretty jazzed about the 20th anniversary of Sub Pop, an influential record label with a roster that ranges from grunge legends Nirvana and Soundgarden to indie chart-toppers the Shins and the Postal Service. We celebrated by listening to Executive Vice President Megan Jasper's 21 favorite releases, then told you about a few of our own. We talked to Fleet Foxes about what being on the label means to them, and we even went straight to the source with a VIP tour of Sub Pop HQ. In case you're still fuzzy on what makes the label a musical treasure, get caught up with this quick three-minute history.
