David Van Cortlandt Crosby (born August 14, 1941) is an American guitarist, singer, and songwriter. In addition to his solo career, he was a founding member of three bands: the Byrds; Crosby, Stills & Nash (CSN, who are sometimes joined by Neil Young as Crosby, Stills, Nash and Young [CSNY]); and CPR.
He wrote or co-wrote “Lady Friend”, “Why”, and “Eight Miles High” with the Byrds and “Guinnevere”, “Wooden Ships”, “Shadow Captain”, and “In My Dreams” with Crosby, Stills & Nash. He wrote “Almost Cut My Hair” and the title track “Déjà Vu” for Crosby, Stills, Nash & Young’s 1970 album. He is known for his use of alternate tuning and jazz influence (notably on “Eight Miles High”, “Wooden Ships”, and “Déjà Vu” and with his group CPR).
Crosby has been inducted into the Rock and Roll Hall of Fame twice: once for his work in the Byrds and once for his work with CSN. Five albums he contributed to are included in Rolling Stone’s 500 Greatest Albums of All Time, three with the Byrds and two with CSN(Y). He has been depicted as emblematic of the 1960s’ counterculture.
