In October 2006, Chris DeWolfe, CEO of MySpace, led the Rock For Darfur campaign, a concert series touring across the United States showcasing big-name bands devoted to raising funds - and consciousness - for the Darfur crisis. A portion of the proceeds will go toward the Oxfam America's Sudan Crisis Relief and Rehabilitation Fund.
