Muse, Arcade Fire, Phish To Headline Outside Lands Festival

MGMT, Girl Talk, Big Boi and deadmau5 also on the bill of the three-day San Francisco event scheduled for August.

If you've never been to San Francisco's iconic Golden Gate Park then you may not know that it's the kind of place where barefoot types are very likely to break out into spontaneous dance between bouts of stick juggling and hula hooping.

Which is why the lineup for the 2011 Outside Lands Music & Art Festival is perfect for the historic patch of green in the City by the Bay. The fourth annual edition of the fest, scheduled for August 12-14, will be headlined by Muse, Phish (who will play two sets), Arcade Fire, the Black Keys, MGMT, the Decemberists, Erykah Badu and the Warren Haynes Band.

That eclectic mix of jam-band, techno, indie-rock and arena powerhouses reflects the sonic diversity on the rest of the bill, which will also feature deadmau5, the Roots, Girl Talk, Big Boi, Beirut and Sia playing alongside iconic rocker and Creedence Clearwater Revival founder John Fogerty, New Orleans funk legends the Original Meters, gospel great Mavis Staples and re-formed Clash spinoff group Big Audio Dynamite.

Also on the bill are: Arctic Monkeys, STS9, Josh Ritter & the Royal City Band, Best Coast, Phantogram, Junip, Little Dragon, Foster the People, the Joy Formidable, Major Lazer, OK Go, the Greyboy Allstars, Old 97's, !!!, Latyrx featuring Lyrics Born & Lateef, Phantogram, STRFKR, Toro y Moi, Vetiver, Tamaryn, the Fresh & Onlys and others.

Tickets go on sale on Thursday at the Outside Lands website, and a significant part of proceeds from every ticket will benefit San Francisco's Recreation and Park Department.

Last year's Outside Lands event also featured a similarly diverse variety of artists, including Kings of Leon, the Strokes, My Morning Jacket, Janelle Monáe, Al Green, and Nas and Damian "Gong" Marley.
