Crosby Stills & Nash

"His legacy will continue to live on through his legendary music," Crosby's wife said in a statement.

An informal jam at a party in July 1968 showed David Crosby, Graham Nash and Stephen Stills that their voices blended perfectly together.

Crosby Stills and Nash's 1969 song 'Helplessly Hoping' appears in Alex Garland's 2018 sci-fi film 'Annihilation.'

Shortly after releasing their debut album, Crosby, Stills & Nash brought Neil Young on board.

This self-titled debut remains one of the rare records that lived up to the hype around it.
