On two magical nights-- June 22, 2005 and September 12, 2006-- punk godmother Patti Smith and My Bloody Valentine genius Kevin Shields took the stage together at London's Queen Elizabeth Hall. Their collaboration was called the Coral Sea, and took both its name and inspiration from Smith's 1996 book The Coral Sea. The book and the performance served as tributes to the legendary late artist Robert Mapplethorpe, who was Smith's close friend. (He took the iconic photograph that appears on the cover of Smith's 1975 debut album Horses.) - Source
