Megadeth is an American thrash metal band formed in 1983 after former Metallica lead guitarist, Dave Mustaine, was fired for aggressive, drunk behavior. Megadeth is one of the "big four" of thrash metal alongside Metallica, Slayer, and Anthrax. Their current members are Dave Mustaine(Lead/Rhythm Guitarist), David Ellefson(Bass Guitar), Chris Adler(Drums on their new album, only for session), and Kiko Loureiro(Lead Guitar). They currently released their 14th album, Super Collider. Super Collider is the first album, since Cryptic Writings, to not have a lineup change. It is also David Ellefson's second album since his reunion with Megadeth back in 2010, just in time for the Big 4 show.
