These musicians say they're angry Americans too--just at the guy running the place. This October an A-list collection of artists, including BRUCE SPRINGSTEEN, the DAVE MATTHEWS BAND, BONNIE RAITT, the DIXIE CHICKS and PEARL JAM will kick off Vote for Change, a 34-city tour to help the liberal group America Coming Together unseat President Bush in November. "I'm afraid of the attitude of the people in the White House right now," says Matthews. "This is the most important election of my lifetime, and if I don't say anything, it will sit badly in my heart." Whether the tour will change votes or face a backlash isn't yet clear. But its all-swing-state lineup should guarantee a first: New Yorkers will have to hit Philly for the season's hot show.
