Megadeth
Megadeth is one of the few American thrash metal bands from the 1980s to be successful. Megadeth is thought of as one of the "Big Four" of thrash metal, along with Metallica, Anthrax, and Slayer. These bands were important because they made thrash metal much more popular. Loudwire ranked Megadeth the third-best thrash metal band of all time, behind Slayer and Metallica. Billboard said that Peace Sells... but Who's Buying? is a "landmark of the thrash movement". They thought that what the album was about is still important now.
