9. 'Wrecking Ball'
For his newest album, Wrecking Ball, Springsteen ditched his longtime producer Brendan O'Brien in favor of Ron Aniello, best known for his work with Guster and Candlebox. "The record basically started out as folk music – just me and a guitar singing these songs," says Springsteen. "Then Ron brought a large library of sound that allowed me to explore, like maybe a hip-hop drum loop or country-blues stomp loop. The actual drums came later. There was no preconceived set of instruments that needed to be used. I could go anywhere, do anything, use anything. It was very wide open." The songs were written before the Occupy Wall Street movement began, but they voice much of the same anger towards Wall Street greed. "This is as direct a record as I ever made," Springsteen tells Rolling Stone. "That's with the possible exception of Nebraska, which this record has a lot in common with."
