`After Buffalo Springfield disbanded, Stills began working with David Crosby and Graham Nash as the trio called Crosby, Stills & Nash (CSN). In addition to writing many of the band's songs, Stills played bass, guitar, and keyboards on their debut album. The album sold over four million copies and at that point had outsold anything from the three members' prior bands: the Byrds, Buffalo Springfield, and the Hollies.`
