Good stuff!
11 on the other list was way too hard! I think I can do 20
Just don't ask me to rate them, I'm just doing 20 brilliant thrash records by 20 bands. I'm also leaving off the brilliant Celtic Frost, Bathory and Venom and just focusing on the bands that were thrash to me. I'm gonna leave off great records by Suicidal Tendencies, Crumbsuckers, DRI, Ludichrist, Cro-Mags & Agnostic Front for the same reason.
Metallica - Kill em All
Slayer - Hell Awaits
Anthrax - Spreading the Disease
Megadeth - Killing is My Business
Sodom - Agent Orange
Dark Angel - Darkness Descends
Exumer - Possessed By Fire
Possessed - Seven Churches
Whiplash - Power & Pain
Deathrow - Life Beyond
Protector - A Shedding of Skin
Destruction - Eternal Devastation
Detente - Recognise No Authority
Coroner - Punishment For Decadence
Death - Scream Bloody Gore
Sepultura - Beneath the Remains
Hexenhaus - A Tribute to Insanity
Kreator - Pleasure to Kill
Vio-Lence - Eternal Nightmare
Exodus - Bonded By Blood
Okay once again I've run out of space and there are still records that thoroughly deserve to be up there so five more
Overkill - Taking Over
Sabbat - Dreamweaver
Sacrifice - Torment in Fire
Testament - the Legacy
Holy Moses - Queen of Siam
And still no room for the excellent Annihilator, Death Angel, Forbidden, Vendetta, Iron Angel, Flotsam & Jetsam, Onslaught, Atrophy, Artillery, Razor, Nuclear Assault, S.O.D, Darkness, Agent Steele, Cyclone, Mortal Sin, Angel Dust, Vektor, Realm and any number of others that might have made this list if I'd have thought of them.
