Hoping to score 3-day passes to this summer's Pitchfork Music Festival? Well, you've missed your chance.

The annual music festival that has become a staple in Chicago's summer entertainment scene sold out in two days, in advance of today's announcement that the Dirty Projectors, Flying Lotus, Sleigh Bells and eight more bands and artists would be added to the lineup.

"Well, that was fast!" festival organizers posted on the namesake music blog, noting that still more performers would be announced as the July 13-15 weekend approached.
