Crosby, Stills and Nash was an influential American group formed in 1968 in California, consisting of David Crosby, Stephen Stills, and Graham Nash. Known for their vocal harmonies and a blend of pop and folk rock, the group sometimes included Neil Young, then called Crosby, Stills, Nash and Young. With backgrounds in bands like The Byrds, Buffalo Springfield, and The Hollies, the members created classics such as Guinnevere, Suite Judy Blue Eyes, Marrakesh Express, and Teach Your Children. The group played at Woodstock in 1969 and was inducted into the Rock and Roll Hall of Fame in 1997. They performed at the Globen arena in Stockholm in 2005.
