Megadeth
On April 11, 1983, Metallica fired Dave Mustaine before they released their first album, Kill 'Em All. This was because he was addicted to drugs. He also had problems with James Hetfield and Lars Ulrich. Mustaine was one of the first members of Metallica. He made some of the band's first songs. After he was fired, Mustaine wanted to make a band that had faster, better music than Metallica. While he was riding a bus to Los Angeles, Mustaine read an advertisement by Senator Alan Cranston that had the word "megadeath" in it. He liked the word, and wrote a song named "Megadeth".
