Exorcist
Nightmare Theater, I've never even heard of the band, so I guess that proves your point. I'm sure it's a great CD and one I will have to look for.
Hallows Eve,
Death And Insanity is a great disc with more than a few good songs and I agree with Rigor Mortis, a great debut!
Coroner, why oh why did I trade their R.I.P. CD!
Other good thrash bands, other than the obvious big names.
Blood Feast -

Defiance - Bay area band, Steev Esquivel (Skinlab) sang on their second and third CDs.
Dementia.
Exumer - German band like Kreator Destruction.
Still, a ton more could be listed!
DELIRIOUS - do they have a website? I'm always on the lookout for new bands.
Another new GERMAN thrash band is Witchburner

True thrash in the Sodom style. I have a CD from them called
Blasphemic Assault but they also have a new one out which I have not heard.
