Opening Lou Reed's 1972 solo album, the hard-riffing "Vicious" actually traces its origin back to Reed's days with the Velvet Underground. Picking up bits and pieces of songs from the people and places around him, and filing his notes for later use, Reed said it was Andy Warhol who provided fuel for the song. "He said, 'Why don't you write a song called 'Vicious,'" Reed told Rolling Stone in 1989. "And I said, 'What kind of vicious?' 'Oh, you know, vicious like I hit you with a flower.' And I wrote it down literally."
