For a lot of music festivals, it would have been enough to simply book the 13 acts that Pitchfork initially announced as part of the lineup for this summer's seventh annual live extravaganza -- including Vampire Weekend and Feist. But ticket holders will get a little extra bang for their concert dollar thanks to the 11 additional artists that were just announced, a group led by Dirty Projectors and recent 'SNL' performers Sleigh Bells.

Full three-day passes are already sold out for this year's Pitchfork Music Festival, which will be held July 13-15 at Chicago's Union Park. Single-day tickets will be sold for $45 -- which might sound a little pricey, at least until you feast your eyes on the full list of performers that the organizers have announced so far. Heck, even the notoriously picky Pitchfork staff might have to give it a 10. Take a look below:
