This is probably the ultimate folk-rock album. Crosby, Stills, Nash (& Young)’s debut was already a massive success, but “Déjà Vu” surpasses it once again, at least in terms of sales and impact. With the addition of Neil Young and his rock-oriented guitar, the album became significantly more folkROCK than its predecessor, though the quartet managed to strike a balance between ballads, folk songs, protest songs and rock songs. The characteristic harmonies of the core trio (supplemented here and there by Neil Young’s falsetto) dominate the sound. A true classic of the genre and of rock history in general.
