Grohl talks about his journey from playing small punk clubs to giant stadiums in his new memoir, 'The Storyteller.' He reflects on how he taught himself drums, his friendship with Kurt Cobain, and reinventing himself after Cobain's death. "I was heartbroken," he says. "I didn't really know if I ever wanted to play music again, until I realized that music was the one thing that had healed me my entire life." Grohl joined us from his studio, and also played a few songs.
