Kings Of Leon, Jay-Z, Dave Matthews Band, Stevie Wonder Headlining Bonnaroo 2010

The lineup for the 2010 Bonnaroo Music & Arts Festival is beginning to take shape... sllllllloooooowwwwwlllllly.

The folks behind the Manchester, Tenn.-based festival have been revealing the lineup one band at a time through their Twitter (hey, they have to upstage Coachella somehow, right?) and MySpace. Here's what we can tell you so far:

Jay-Z, Stevie Wonder, Dave Matthews Band and Kings Of Leon will headline the four-day festival, which takes place June 10 to 13. That means you're significantly less likely to see fans downing psilocybin-laced Reese's peanut butter cups at the hippie-friendly festival due to Phish's absence, but we still wouldn't rule it out.

The Flaming Lips will perform their version of Pink Floyd's The Dark Side Of The Moon at the festival, which will also feature appearances from Weezer, The Dead Weather, OK Go, The XX, Regina Spektor, Phoenix, The National, Michael Franti & Spearhead, Japandroids, GWAR, She & Him, Punch Brothers, Thievery Corporation, The Avett Brothers and Chromeo, among others.

Tickets are on sale now through the Bonnaroo website. Four-day general admission tickets will run you $234.50 U.S. (about $251 Canadian) until those are sold out, at which time the price will be increased to $249.50 U.S. (about $267 Canadian)
