The Silversun Pickups played a benefit concert at the Echoplex for the Pablove Foundation in April of 2009. It was a great show. This track is "Panic Switch" from the album Swoon.
Since a few people have asked I'll add that I wasn't clever enough to get a feed out of the sound board and that my camera audio sounded a lot like gravel in a blender so this is the actual track mixed in over the performance. They sounded pretty much exactly like that so I hope it doesn't ruin it for you.
