SPRINGSTEEN RULES: Boss Leads Dave Grohl, Joan Baez in Epic All-Star Jam at Power to the People Fest...

Bruce Springsteen closed out the inaugural Power to the People Festival on Saturday with a sprawling jam that grew from a solo performance of his protest track "Streets of Minneapolis" into a full-cast finale. Joan Baez joined him for Dylan's "Chimes of Freedom," Tom Morello added guitar work through Clash and Springsteen covers, and the stage kept filling—Dave Matthews, Nathaniel Rateliff, and Dave Grohl cycling through before the entire day's lineup converged for "This Land Is Your Land" and "Power to the People." The festival, held in Maryland, positioned itself as a benefit around activism and solidarity.
