Our own Len Comaratta turned in one heck of an interview with The Smashing Pumpkins frontman Billy Corgan, but KROQ got something out of Corgan that Len didn’t: an in-studio acoustic performance. After sitting down for a chat on the L.A. radio station’s The Kevin & Bean Show, Corgan switched over to Studio R for a performance of “The Celestials” and “One Diamond, One Heart” from the latest Smashing Pumpkins record, Oceania. Check out the clips at KROQ; and no worries, Len, you’re still our favorite interviewer.
