Megadeth is an American thrash metal band led by singer/guitarist Dave Mustaine. The band is considered one of the "big four" of American thrash metal, along with Slayer, Anthrax and Metallica (Mustaine thinks that Exodus should belong in this group too). Many of the band's songs focus on politics, war, and the military.

Mustaine was originally a member of Metallica and has writing credits on the band's first two albums: Kill 'em All and Ride The Lightning.

Besides Mustaine on lead, Marty Friedman shared many solos within Megadeth, being noted for his specific and unique scale/solo style, and further branding the very well known sound of Megadeth through the late 80's/early 90's. He later left Megadeth.

Megadeth formed in 1983, disbanded in 2002 due to an arm injury suffered by Mustaine, and reformed in 2004. The band's lineup has changed multiple times, with only Dave Mustaine remaining constantly throughout the years (although bass player David Ellefson remained in the band from 1983 until 2002).

Megadeth's new album "United Abominations" was released 15. May 2007.

Megadeth was recently seen on Gigantour along with Lamb of God, Opeth, Arch Enemy, Overkill, Into Eternity, Sanctity, The SmashUp and more.
