Sigur Rós kicked off their first live tour in four years Sunday night at the Mann Center in Philadelphia, in support of their new release, Valtari. Tonight, the band - which has reportedly grown to 11 members - comes to the Prospect Park Bandshell: a benefit show for Celebrate Brooklyn that's been sold out for months. If you're not one of the lucky few with a ticket, the good folks from NPR Music will be streaming the concert live online, starting at 8:30. Or, just make like I do and set up a picnic outside the baggie. 

Set lists from the Philly shows below. Watch the video above for an idea of what to expect tonight.
