Well, jesus. Ty Segall and company showed up on Letterman last night to play “You’re The Doctor,” a standout from Segall’s recent release and one of our favorite records this year, Twins. The song is barely on the rails before it descends into a chaotic noise freakout, punctuated by a scream of “GO VOTE” by Segall. Pretty heartening to see this craziness broadcasted on network tv. Check the clip below.
