The music world came together Thursday to mourn singer David Crosby — known for his work with the Byrds and Crosby, Stills, Nash & Young — after his death at age 81.
Among those paying tribute on social media was Graham Nash, who was part of the folk-rock quartet with Crosby, Stephen Stills and Neil Young. In an Instagram post, Nash shared news of his longtime collaborator's death and reflected on their decades-long friendship.
"I know people tend to focus on how volatile our relationship has been at times, but what has always mattered to David and me more than anything was the pure joy of the music we created together, the sound we discovered with one another, and the deep friendship we shared over all these many long years," Nash wrote. The guitarist shared a vintage photo of his guitar case next to another that bore Crosby's name.
