Reed and Cale recruited Reed's college acquaintances, guitarist Sterling Morrison and drummer Maureen Tucker, to join a band they called the Velvet Underground. The group soon caught the attention of artist Andy Warhol, who incorporated them into his regular parties and introduced them to the New York art scene. Warhol claimed some ownership of the band, compelling them to take on European model Nico as a singer on their debut album. Despite their resistance, the first Velvet Underground album, called The Velvet Underground & Nico, is considered one of the most influential in rock history. Some of Reed's songs, including "Heroin," addressed his growing drug use.
