Last fall, music producer Hal Willner gathered a group of heavy-hitting musicians to raise money for the Clinton Foundation, with a set list honoring the 50-year-old Freedom Rides movement that stormed buses in the American South. Clips from the concert -- which featured Tao Seeger, Eric Mingus, Tim Robbins and Lou Reed among others -- are slowly leaking out via Dailymotion, one of Willner's sponsor. Below, check out Lou Reed's horn-heavy version of "Who Am I?" from the Highline Ballroom that night. You can stream the full concert at Dailymotion's Music In Motion channel.
