Kill 'em All

This was the first album released after kicking Dave Mustaine out of the band. This album was released on July 29, 1983. The album was a little more than 51 minutes but contained 10 amazing and powerful songs the metal world had ever seen. The initial publication only made 1500 copies of the album, but to many people’s surprise the album soared to selling over 3 million copies in the United States alone. This one step opened the door for hundreds of other bands like Slayer, Anthrax, and Megadeth.
