Billy Corgan, who is just Billy Corgan again now, for the record, has stopped by everyone's favorite unconventional concert spot—the much hallowed NPR Tiny Desk. The 12-minute concert sees Corgan performing two tracks from his new album Ogilala, "Aeronaut" and "Mandarynne," as well as the Smashing Pumpkins' iconic track "Tonight, Tonight."He's accompanied by a string quartet, and even though it's kinda weird to see a man in a cap and a puffer jacket, accompanied by a string quartet, it's good fun. Corgan himself switches from guitar to piano, and it's a pretty blend of old and new, though "Tonight, Tonight" is the standout by miles. See it above.Follow Noisey on Twitter.
