Among his other endeavors, Andy Warhol managed a band,
Lou Reed and the Velvet Underground. 

The only song that would become a popular hit was Lou Reed’s deceptively upbeat,
“A Walk on the Wild Side.”

Although the group experienced little commercial success, the Velvet Underground is often cited by critics as one of the most important and influential groups of all time. In a 1982 interview Brian Eno made the statement that while the first Velvet Underground album may have sold only 30,000 copies in its early years, “everyone who bought one of those 30,000 copies started a band.” – WIKIPEDIA

Remember Andy’s photographer buddy, Nat Finkelstein?
Nat didn’t like Lou and the Velvet Underground.
He called them “The Psychopath’s Rolling Stones.”

Lou Reed responded by saying,
“The three worst people in the world are Nat Finkelstein and two speed dealers.”
