Towering above virtually everything that Graham Nash has accomplished in his long and multi-faceted career, there stands the litany of songs that he has written and introduced to the soundtrack of the past half-century. Two-time Rock and Roll Hall of Fame inductee Nash burst on to the scene during the British Invasion with The Hollies before he formed the legendary supergroup Crosby, Stills and Nash in 1968 with David Crosby and Stephen Stills. As Nash prepares to launch a European tour in July, Rhino looks back at some of his best-known recordings from the past 50 years in a new anthology featuring more than a dozen unreleased demos and mixes.
