A superstar collaboration between three members of already prominent bands - The Byrds (David Crosby), Buffalo Springfield (Stephen Stills) and The Hollies (Graham Nash). After parting with their parent bands, the trio united to create a melodic and highly successful fusion of pop and folk-rock distinguished by their intricate vocal harmonies, both with and without occasional member Neil Young. They reputedly began after an impromptu jam session at a party hosted by singer Cass Elliot and their self-titled 1969 debut album was an immediate success - including two smash hits, Marrakesh Express and Suite: Judy Blue Eyes. With Neil Young joining, the band played their second live gig at the legendary Woodstock Festival, where they became iconic symbols of the hippy era, later scoring a major hit with Joni Mitchell's commemorative song Woodstock about the festival. They scored another major hit with Teach Your Children but internal tensions erupted and they split in 1970. The band reunited briefly in 1973 and again in 1977 (without Young), reaching Number 2 with the beautifully crafted CSN album (including another major hit, Just A Song Before I Go). But there was another lengthy lay-off while they concentrated on individual projects until they hit the heights again with the 1982 album Daylight Again and supporting tour. As Stills overcame persistent drug problems and spent time in prison, their output became sporadic but while mass success subsequently eluded them, the group continued to make occasional records and tours.
