The FYF Fest has released the lineup for the annual day-long shindig, which will occur on Sept. 4 at the Los Angeles State Historic Park downtown. The festival, put on by FYF Productions, features a virtual who's who of the underground rock scene, and this year includes, among dozens of others, performances by dance-punk luminaries the Rapture, Panda Bear (of Animal Collective), stoner-rock legends Sleep (who will be performing half of their epic "Dopesmoker," and half of their "Holy Mountain"), Dead Man's Bones, !!!, the Mountain Goats, Ted Leo & the Pharmacists, Wavves, Best Coast, and the rest of the list that appears to your right.

The festival will occupy the same location that has been then center of concerns of late after the annual Hard L.A. electronic music festival announced that it was canceling its July 17 concert and merging it with the upcoming Hard Summer festival on Aug. 7. Last year's FYF Fest went off without a hitch at the park (though some attendees endured a long wait in line before gaining admission), and ended up being one of the festivals of the year.

In fact, FYF has been on a roll of late. Last month it was announced that the company would be co-promoting the upcoming Matador 21 party in Las Vegas, and just yesterday released news of two upcoming weekend performances by One Day As a Lion, the new band fronted by Rage Against the Machine's Zack de la Rocha.
