The 19,000 people crowded into San Jose, CA's HP Pavilion Wednesday night for Bruce Springsteen and the E Street Band's kickoff to the Working on a Dream tour provided a snapshot of a generation. Many had Blackberries and receding hairlines; some sported gray ponytails; a few brought their teenagers along. But the minute the music started, none of that mattered, because Bruce and his band... well, you already know that they can rock. What you might not realize, until you see them live, is just how fresh their energy is, and how relevant Springsteen's music remains. Anyone looking for a nostalgia-fest was in the wrong place. Springsteen has kept busy writing songs that explore the nuances of a struggling middle-class America.
