Metallica is an American heavy metal band from Los Angeles, California, formed in 1981.
James Hetfield wrote the song while he was on the phone with his then girlfriend. Since he held the phone with one hand, he plucked the four open strings of a standard E-minor chord with the other, which eventually made up the first two bars of the song.
Apocalyptica, a band that plays metal music using primarily 4 cellos, covered this song on their album Inquisition Symphony.
