David Crosby was an American singer, songwriter, and harmony‑driven innovator whose voice and curiosity shaped multiple eras of modern folk and rock.

Born in 1941 in California, he first gained recognition with The Byrds, helping bring rich vocal blends and jangling guitars into the mainstream. He later co‑founded Crosby, Stills & Nash, where his intricate harmonies, open‑tuned guitar work, and reflective songwriting became essential to the group’s sound. Crosby’s music often explored vulnerability, idealism, and personal searching. Despite a turbulent life, he remained creatively restless, releasing thoughtful solo work and collaborating widely, always guided by a deep love of musical interplay.
