Forbidden - the first 3, but especially "Twisted Into Form"
Testament - the first 4
Defiance - "Void Terra Firma" and "Beyond Recognition"
Sadus - all but the first one
Megadeth - the first 4
Anthrax - most of 'em
Antithesis - both
Vio-Lence - "Oppressing the Masses"
Sacred Reich - the first 3
Flotsam and Jetsam - the first 3 (weren't really thrash after that, but I still like 'em a lot)
Metallica - through AJFA (if you consider them thrash, which is debatable)
Pantera - "Cowboys From Hell"
alright, I could keep going but I'm getting tired. That covers a lot of the greats.
