"Very few people have any idea of Tim Buckley other than as Jeff Buckley's father, or maybe as a folkie from the late sixties. Those labels hardly begin to scratch the surface of his musical genius, as uncommercial as it may have been at the time. But few who have looked at his full career can deny that he had a talent like few others, and a voice that, I believe, is still unmatched.
"Tim Buckley (February 14, 1947 – June 29, 1975) was an American singer/songwriter. He began his career based in folk rock, but subsequently experimented with genres such as psychedelia, jazz, the avant-garde, and funk paired with his unique five-octave vocal range.
Buckley died at the age of 28 from a heroin and morphine overdose. He left behind one biological son, Jeff, who himself was a highly regarded singer who died young, as well as an adopted son, Taylor."
