GUITARS!: Neil Young and Crazy Horse

Updated 4:15 p.m. Now that JazzFest is over, it's time for the slow trickle of news about this year's Voodoo Fest lineup to start. The punk rockers with pop levels of success, Green Day, announced via Fuse TV and on their website that they will be one of the headliners at the 2012 edition of the Halloween weekend festival. The City Park engagement will be the only North American tour date this year, according to the report. Also among the headliners: Neil Young and Crazy Horse, and for electronic fans, the highly acclaimed Justice and recent Buku headliner Skrillex.

Among other acts announced today: the rock supergroup featuring Mike Patton and ex-Jesus Lizard guitarist Duane Denison known as Tomahawk, pop-punkers Say Anything, longtime George Clinton sidekick Bootsy Collins, fresh-from-JazzFest bluesman Gary Clark Jr. and Preservation Hall Jazz Band.

Coming off their Broadway musical American Idiot, the band is set to release a trio of albums in four months this fall titled '¡Uno!,' '¡Dos!' and '¡Tre!', respectively. The first album is scheduled to be released in September, meaning it will be out in time for the Halloween weekend festival. Green Day last played Voodoo in 2004.

Meanwhile, Young and his more-than-backing-band, Crazy Horse, have a new album titled Americana that's set to come out June 5. It's their first collaboration in nine years, and features the band returning to the same kind of ideas that informed them during their heyday: taking classic American songs and reworking them into extended, fuzzed-out workouts. These days, the band is taking those songs literally on their face, as the first single from the album is "Oh Susannah." Next? "She'll Be Coming Round the Mountain." In any case, this will not be the legendary outfit's only U.S. tourdate this year, as a summer swing is planned through Red Rocks Ampitheatre in Colorado and Golden Gate Park in San Francisco.

FIlling out the heavier, more experimental category that Voodoo has never feared, Tomahawk, whose members have been in bands like Mr. Bungle, Faith No More, the Melvins, Battles and the aforementioned Jesus Lizard, are also due for a new album in the fall. Earlier this year, they added Trevor Dunn of Secret Chief on bass to the original lineup.

Voodoo also announced the Fest will allow onsite camping for the first time this year, with general camping and a "luxurious, all-encompassing camping experience" available.

And that's only the first crack. Judging from how Voodoo rolled out their lineup last year, they'll be announcements coming out all summer long.
