Carry On is a 4-CD career retrospective box set by Stephen Stills (not to be confused with the CSN compilation released in 1991). It features highlights from his career as a solo artist and with groups including The Au Go Go Singers, Buffalo Springfield, Manassas, and various permutations of CSN&Y. The tracks are arranged in general chronological order of release. The album also includes previously-unreleased material. The album was compiled by Graham Nash, who also compiled box sets for himself and for David Crosby.
