Given how quickly the Pitchfork Music Festival sold out of its three-day passes, it appeared that fans would've been content with the lineup as first announced. But of course, that would leave a lot of dead air during the weekend-long (July 16-18) extravaganza in Union Park -- so here comes round two, led by Canadian pop collective Broken Social Scene, dissonant hip-hop producer/MC El-P, Animal Collective's Panda Bear, fusion group The Jon Spencer Blues Explosion and Chicago-based psych acts Cave and Alla.

Below is the complete day-by-day lineup as we know it so far, with the newly announced acts starred.
