Deja Vu is CSN's best album. A big reason of this is Neil Young. CSN were great together, but when they joined with Young, the possibilities were endless. This album shows that. Crosby wrote two great songs on the album; Almost Cut My Hair and Deja Vu. Graham Nash also wrote some great songs, including one of the best songs they ever did, Teach Your Children, and also Our House. Stills and Young really shine on this album, collaborating on the great Everybody I Love You. Individually, Stills wrote such classics as Carry On and 4 + 20. Young wrote Country Girl, which is a great song, but Helpless may just top the album as the best song on it. With these four incredible songwriters on one album, how did they ever find room for Joni Mitchell's Woodstock? I don't know, but I'm glad they did, because it is a great song. This album is very essential to any fan of any of the four artists.
