For Warren Zanes, music has been a salvation. In his troubled teen years, his brother put him in the band The Del Fuegos. Then music was the conduit to his PhD. And now, after a lifetime of seeing himself as just another guy without a father, Warren’s music biographies have helped him feel at home with other lost people. Warren and Marc talk about explaining life through music, writing about Tom Petty, and Warren’s new book Deliver Me from Nowhere: The Making of Bruce Springsteen’s Nebraska.
