Metallica was formed in Los Angeles in late 1981 when Danish drummer Lars Ulrich placed an advertisement in a Los Angeles newspaper, "The Recycler", which read, "Drummer looking for other metal musicians to jam with Tygers of Pan Tang, Diamond Head and Iron Maiden." Guitarists James Hetfield and Hugh Tanner of Leather Charm answered the advertisement. Although he had not formed a band, Ulrich asked Metal Blade Records founder Brian Slagel if he could record a song for the label's upcoming compilation album, "Metal Massacre". Slagel accepted, and Ulrich recruited Hetfield to sing and play rhythm guitar. The band was officially formed on October 28, 1981, five months after Ulrich and Hetfield first met.
