Unless you've been hiding under a rock, you've probably heard of San Francisco's Outside Lands Arts & Music Festival. And if you're reading this, you probably aren't there. Luckily, you can still be part of the (peripheral) mix. Starting at 2pm PST today and running through Sunday, catch a live webcast on YouTube straight from Golden Gate park with performances by Thievery Corporation, Silversun Pickups, Jason Mraz, Atmosphere, Cage the Elephant, and many more. Next year, get yourself up there. . . and take your sweater.
