The music of Crosby, Stills and Nash, and especially their 1969 self-titled debut album, exemplified the Woodstock generation – three men, three voices, one common view of freedom and justice. Their decision to recruit Neil Young before their first public performance fundamentally altered CSNY the band dynamic. Worldwide acclaim and success followed: their first three albums, released 1969-1971, have sold almost 30 million copies. In 1974 they embarked on the biggest stadium tour then attempted, playing baseball and football stadiums and racetracks across the US to thousands of fans. They were also pop stars, securing nine top 40 singles between 1969 and 1982. And yet, today, with Neil Young regarded as a musical legend with a classic back catalogue, his colleagues Crosby, Stills and Nash remain far less acclaimed. They comprised Crosby: the drug-addled hippy with weird songs and golden voice, Stills: the blues man and guitar genius and Nash: the hard-as-nails balladeer with a strong social conscience. Together, at their best, they were unbeatable. This book tells you why, aiming to set things straight, with an album by album analysis of CSN’s five studio albums, as well as the three they made with Neil Young.
