The singer Chris Cornell performs with Audioslave in Havana Friday May 6, 2005. The concert, hastily organized by the government's Institute of Music, is being billed as Cuba's first outdoor rock concert by a U.S. band, though some Cuban artists have disputed that claim. Friday's show at the Anti-Imperialist Tribunal certainly has the potential to be Cuba's largest, far bigger than the few relatively controlled indoor concerts involving artists such as Billy Joel and Bonnie Raitt (AP Photo/Jorge Rey)
