The story of how Crosby, Stills and Nash first sang together has been told many times — at Joni Mitchell’s house in Laurel Canyon in 1968, the three of them harmonizing for the first time and producing a sound that has been described by all three participants and by the people who were present with the specific vocabulary of people describing something that exceeded expectation in the most complete possible way. David Crosby has said it was the most beautiful sound he had ever made. Stephen Stills has said he knew immediately they were going to be famous. Graham Nash has said he stood very still because he was afraid that moving would break whatever was happening.
The moment has been described so many times that its specific texture has been worn smooth by repetition. What has been told less often is the specific night when Neil Young joined the configuration and the four-part harmony that the name CSNY implies was produced for the first time — not on a record, not at a planned session, but at a gathering that was social rather than professional, in circumstances that neither the music press nor the music business had organized or anticipated.
Young was the addition that none of the existing three had expected in quite the way that it happened — he and Stills had history, had played together in Buffalo Springfield, had the specific combined creative tension of people who had built something together and whose combination produced music that neither produced alone. When Young played alongside the three-part harmony that Crosby, Stills, and Nash had developed, what happened was something that the accounts of people present have described with a consistent reference to surprise — the surprise of hearing a fourth element added to a configuration that had seemed complete and discovering that the fourth element made the configuration more complete rather than simply larger.
Crosby has said the first night the four of them sang together was the night he understood what a harmony could be when each voice was genuinely irreplaceable. He has said this knowing what Crosby, Stills and Nash alone produced, which was already extraordinary — and he has said it as a distinction, a description of something qualitatively different rather than quantitatively greater.
The subsequent history of CSNY is the history of the most productive and most acrimonious supergroup in rock history — a configuration of four people each of enormous talent and enormous ego who produced music of extraordinary quality and who found sustained professional cooperation among the most difficult things any of them had attempted. They reunited and separated multiple times. The reunions produced albums and tours of significant commercial and occasional artistic achievement. The separations produced the specific bitterness of people who had experienced something together that they could not recreate with the same quality alone.
Crosby died in January 2023. He was 81. His accounts of the first night the four of them sang together were among the most consistent and most specific things he gave in fifty years of interviews — the memory of a sound that he heard once, in the specific configuration that produced it, and that he spent the rest of his life trying to return to.
