Megadeth is a heavy metal band from the United States. Dave Mustaine started the band in 1983 after Metallica fired him. Megadeth is a member of the "Big Four" in thrash metal along with Metallica, Slayer and Anthrax. Megadeth is one of the creators of thrash metal. They have released 15 albums of music. The band's music is complex, with fast rhythm and difficult guitar solos.
In 1985, Megadeth made its first album, named Killing is My Business... and Business is Good!. The Combat Records record label released the album. After the album came out, larger record labels noticed Megadeth, and the band joined Capitol Records. Their first album with Capitol Records, Peace Sells... but Who's Buying?, was released in 1986. Some Megadeth band members were addicted to drugs, so they got a lot of bad publicity during the 1980s. The band has released many popular albums, such as So Far, So Good... So What! in 1988, Rust in Peace in 1990, and Countdown to Extinction in 1992.
Megadeth has had many different guitarists, drummers, and bassists. Mustaine is the last member of the original group who is still in the band. The band broke up in 2002 when Mustaine had an arm injury, but got back together in 2004. Megadeth's current members are guitarist and singer Dave Mustaine, guitarist Kiko Loureiro, drummer Dirk Verbeuren and bassist James LoMenzo.
