Smashing Pumpkins devotees Silversun Pickups brought "Panic Switch" to Letterman's stage last night, earning rave reviews from the likes of Dave and Paul, who give their special love to the drummer. The performance was pretty energetic, way more so than their languid Unplugged session from a few weeks back, and Silversun Pickups seem pretty confident on the big stage. 

Silversun Pickups' Swoon is out now.
