Crosby, Stills, Nash & Young

They started in 1968 as Crosby, Stills & Nash, formed from former members of three prominent 1960s groups: The Byrds (David Crosby), Buffalo Springfield (Stephen Stills) and The Hollies (Graham Nash). After releasing their first album in 1969, another Buffalo Springfield alum, Neil Young, joined the band.

Joni Mitchell is a huge part of CSN&Y history. She was romantically involved with Crosby before taking up with Graham Nash. She also wrote their song "Woodstock" and did the artwork for their first greatest hits album, So Far, released in 1974. Mitchell's first album was produced by Crosby.

The Crosby, Stills & Nash performance at Woodstock is well documented, but many don't know that with Young, they played the ill-fated Altamont concert headlined by The Rolling Stones. The band left right after their set - before it got violent - because they had another gig that night.
