Without this producer, Bob Dylan would not have broken through like he did—effectively bringing on the swinging sixties and changing music forever. Without this producer, Simon and Garfunkel might have quit before they ever got started, the Velvet Underground might have stayed underground, Frank Zappa might have spent his career recording on hapless independent labels, and jazz greats Sun Ra and Cecil Taylor would definitely have labored longer in obscurity than they already did. This producer helped them all find their voices and realize their visions, revolutionizing American music. He was a Harvard graduate. He was a Republican. He was a black guy from Waco, Texas.
