Graham Nash is an English singer-songwriter from Salford who began his career in the early 1960s in British pop-rock groups and later became part of the North American folk-rock and soft-rock scenes. His work evolved from jangly pop and harmony-driven rock into acoustic-based folk-rock and reflective singer-songwriter material, featuring socially conscious lyrics and rich vocal harmonies which contributed to the development of 1960s and 1970s folk-rock and protest-song contexts.
