David Crosby was the "Byrds" progenitor group psychedelic phenomenon. Graham Nash had known the British beat with "Hollies" Stephen Stills and Neil Young had formed a legend in 1966 "Buffalo Springfield". This balanced meeting of artists (no leader) born "Déjà Vu", an LP where the sound activism and equestrianism loose. It is a branch of the society around them, in the year 1970 with its qualities and defects. This essential album takes several interesting sounds (not a single track is disposable): acoustics optimistic "Teach your children" and pessimistic in "4 + 20" - country in "Helpless" - psychotic in "Carry on" - the raw guitar riffs in "almost They cut my hair" - a challenging and truly sensational pop in "Our House", my favorite track - voices in unison on electric guitars paintings in "Deja vu". This LP is for me one of the symbols of the musical revival era of the first 70 he must possess.
