Come October 17th and 18th, the Treasure Island Music Festival will return to San Francisco’s Treasure Island for its third go around. This particular year promises to feature two days of “stellar and diverse” music, with Saturday geared more toward the electric side of things, while Sunday will offer an indie-like feel.

As a result, the folks behind Treasure Island have tapped MGMT, MSTRKRFT, Girl Talk, Dan Deacon, Passion Pit, Brazilian Girls, LTJ Bukeum, DJ Krush, Murs, Frederico Aubele, The Streets, The Limousines and Crown City Rockers for Saturday and The Flaming Lips, The Decemberists, Beirut, Yo La Tengo, Bob Mould, Grizzly Bear, Sprial Stairs, Sleepy Sun, Thao with the Get Down Stay Down, Tommy Guerrero, Edward Sharpe & the Magnetic Zeroes, Veviter and The Walkmen for Sunday.

Single day tickets ($65.00) and two-day passes ($100.00) will be available via Ticketmaster.com. Pre-sales begin on Tuesday, July 14th.

The complete 2009 bill and additional details will be officially unveiled tomorrow at 12:00 pm PST. Stay tuned as more information becomes available.
