Outside Lands 2012 is on. On August 10th-12th, the annual music and arts festival returns to Golden Gate Park for its fifth year. “Eager Beaver” three day passes go on sale this Friday, March 16th at 12pm PST, for $165 a pop. If last year’s sales trajectory is any indication, these might not last through the weekend.

To stay up to date on all things OSL, follow official festival mascot Ranger Dave on Twitter and Facebook, and sign up for the official newsletter. Also, you can revisit last year’s fun through our OSL 2011 photo gallery and the official 2011 gallery.

Now, any lineup guesses?
