It's The Boss's birthday! Rocker Bruce Springsteen turns 56 today. Famous for his songs about working-class values, Springsteen's songs express what it's like to grow up on New Jersey streets. His most famous albums are Born to Run (1975) and Born in the USA (1984). After the 9-11 attacks, Springsteen gave fund-raising concerts and produced an album, The Rising, with his longtime back-up group, the E Street Band.
