Stills and Young were in Buffalo Springfield. Crosby from the Byrds and Nash from the Hollies joined Stills to form Crosby,Stills, and Nash. Neil Young came aboard after their first album and recorded the album Deja Vu. The band Manassas had Stills and Dallas Taylor (from CSNY) so I took it upon myself to figure you like that sound so you must like those others bands who had the Stephen Stills influence.
