Collective Unconscious once again “drops the needle” on another classic rock album, this time the 1970 release from Crosby, Stills, Nash and Young: “Deju Vu.” You’ll hear hits like “Woodstock,” “Teach Your Children,” “Our House” and “Carry On,” as well as a pulse-pounding rendition of “Almost Cut My Hair” and a selection of other CSNY hits.
