The generally reliable if increasingly snarky music news site the Daily Swarm is citing "multiple industry sources" in reporting that avant-pop dance diva Lady Gaga, punk-pop band turned bombastic stadium rockers Green Day and reunited alternative rockers Soundgarden will be three of the six main-stage headliners when Lollapalooza 2010 rolls into Grant Park on Aug. 6 to 8.
The story doesn't really have any more details than that, though it does note that this will not be Lady G's first Lolla appearance -- "A much less famous Gaga appeared as a brunette in 2007 with a side-stage, daylight time slot, dressed in knee-high fishnets and a disco ball bikini" -- and the site has the pictures to prove it.
Update: Lollapalooza spokeswoman Shelby Meade had no comment.
And another update: My competitor at the Chicago Tribune, Greg Kot, has added two more headliners to the list of acts likely to play Lollapalooza 2010 -- Arcade Fire and the Strokes -- as well as several other up-and-coming names that may take the smaller stages: Yeasayer, the xx, Dirty Projectors, Cut Copy and Hot Chip. He also cites industry sources.
The Sun-Times has been unable to confirm that Nick Drake, Elliott Smith, Jay Reatard and Jeff Buckley also will appear on the bill.
