Back for its 22nd year, the Bridge School Benefit Concert unites socially conscious rockers in the name of a good cause. The Bridge School, which provides education for children with physical impairments, was co-founded by Neil Young, who headlines the show and brings along an eclectic group of top-notch supporting acts. Besides Young, Jack Johnson, Norah Jones, Josh Groban, Sarah McLachlan, Death Cab for Cutie, Wilco, and Cat Power grace the Shoreline Amphitheater stage.
