Thrash Metal is, and will always be my favorite type of music. No matter how many sub-genres or idiotic names some bands give to their music style, they'll never reach the complex "simplicity" of Thrash metal. It's raw, heavy, fast, aggressive, and has a historical impact that probably no other type of heavy metal style will ever reach.

1.Venom - Welcome To Hell

2.Discharge - Hear Nothing See Nothing Say Nothing

3.Suicidal Tendencies - Suicidal Tendencies

4.Metal Church - Metal Church

5.Metallica - Ride The Lightning
