In this episode: In just over a year’s time, Dave Grohl has won five Grammys for his latest Foo Fighters album, released the documentary Sound City, reunited the other surviving members of Nirvana to rock Saturday Night Live with Paul McCartney, and delivered the keynote address at South by Southwest. We talk to Paul Brannigan, author of the biography This Is a Call, about Grohl emerging as a power player in mainstream rock.
Plus: In the addictive video series Black Cab Sessions, artists play acoustic (and sometimes electric) sets in the back of a London taxi. The first signing to the project’s new record label is Wall, a young English singer, songwriter, and producer who turned heads last year with her cover of Karen Dalton's "Something on Your Mind." She joins us in studio to perform live.
