Oops my bad I guess I read it wrong, or I didn't read it, I don't know. South Of Heaven - Slayer

The Teutonic 4 (since the world needs labels) were for me a better group of bands, but as other have said Kreator went really down hill in the late 90's, Destruction was a band I just stopped following and Tankard, well they are Tankard and release music about drinking, it's not like much changed from them over the last 20 years. Even Sodom haven't been the same throughout the 20 years, but they were probably stronger than the other three.

Testament - Practice What Your Preach Sodom- Agent Orange

Largerstein - 25-7

Quartz - Stand Up And Fight

Desecrator - Live Till Death Hidden Intent - Dead End Destiny

Nah it came around before that. Clash Of the Titans was 90-91 depending on where you were in the world and it only had three of the big four. Suicidal Tendencies and Testament supported some countries and Alice In Chains supported others. But it was long after the big four was coined by the media.
