Folk-rock trio Crosby, Stills, and Nash (CSN) – comprised of former members of The Byrds (David Crosby), Buffalo Springfield (Stephen Stills) and The Hollies (Graham Nash) – came together in 1968 when the three members had left their successful groups and formed a new and fresh musical partnership together. With more attention focused on the trio’s unique and ethereal harmonies, CSN became one of rock’s first supergroups with the release of their self-titled debut album in 1969. The album was an international success and included iconic tracks such as “Suite: Judy Blue Eyes,” “Guinnevere,” and “Wooden Ships.” During CSN’s search for a live keyboardist, they floated the idea of bringing Stills’ former Buffalo Springfield bandmate Neil Young on board to handle several instruments. This led to the expansion of the group, who would then be billed as Crosby, Stills, Nash & Young (CSNY). The quartet released the Déjà Vu album in 1970, which was a critical and commercial success, reaching Number 1 on the Billboard 200 Albums chart. Featuring classics such as “Woodstock,” “Our House,” “Teach Your Children,” “Helpless,” and “Almost Cut My Hair,” Déjà Vu became one of the most popular rock albums of the era. They followed that release with the double live album 4 Way Street, which proved to be their final release at the time. Personality conflicts led the group to break up in July 1970 with each member pursuing solo careers while also working on each other’s musical projects. CSNY briefly reunited in 1974 for a tour and the release of the compilation album So Far. While the original trio of CSN reunited several times throughout the 1970s and early 1980s, Neil Young didn’t rejoin his bandmates until the release of 1988’s American Dream, which was the second studio album by the quartet. Neil Young and CSN parted ways again and didn’t come back together for a third album until 1999’s Looking Forward. CSNY undertook tours in 2000 and 2002 and then came together for a final tour in 2006, which resulted in the film and album Déjà Vu Live (2008). David Crosby died on January 18, 2023, at the age of 81.
