Metallica are an American metal band formed in 1981 in Los Angeles when drummer Lars Ulrich posted an advertisement in The Recycler. Metallica’s line-up originally consisted of Ulrich, rhythm guitarist and vocalist James Hetfield, and lead guitarist Dave Mustaine. Mustaine was later fired due to problems with alcoholism and drug addiction - he went on to form the band Megadeth. Exodus guitarist Kirk Hammett took his place. Metallica has been through several bassists, including Ron McGovney, Cliff Burton (who died in a bus crash while the band was on tour), and Jason Newsted. The current bassist is Robert Trujillo, who joined in 2003.
