Known for revolutionizing the music scene starting in the late 1960s, he was still producing music until his last album, Lulu, in 2011. The rockstar's cause of death is unknown, but after a lifetime of hard living, he underwent a liver transplant six months ago. Here, in 2004, a year before his double album The Raven was released, Reed took the stage at the Old Opera House in Frankfurt. Andrew H. Walker/Getty,Andrew H.

How meta. Michael Ochs Archives/Getty Few pictures say rockstar like this one of Reed in his '70s glory. He had a signature method of marrying many genres; in his early work it ranged from avant-garde to street rock, and later from meditation sounds to the poetry of Edgar Allen Poe.

Called a mentor by Reed, Andy Warhol initially managed the Velvet Underground and encouraged them to take on German singer Nico as a collaborator—a move that would later go down in rock history. A number of Reed's songs played homage to Warhol and the eccentric cast of characters that comprised The Factory, Warhol's studio. APDuring the last half century, Reed managed to transform the music scene in New York and worldwide. He will be remembered by his influential discography.
