Top 10 Old School Thrash Albums

I dont know if this old school thrash but Testament's "The Gathering" is amazing
Not at all. Excellent album, though...
I need to listen to more trash. I can't possibly think of ten without mentioning several by the same band.

Actually, I hardly listen to any other trash than Metallica, Megadeth, Voivod and Sodom. I'll look into some of those on your list.
AA! It's fucking thrash, not trash, ffs.
Not ordered, but Reign In Blood is first

Metallica - Ride The Lightning
Megadeth - Peace Sells
Slayer - Reign In Blood (of course)
Testament - The New Order
Metal Church - The Dark
Anthrax - Spreading The Disease (not a huge fan, but that album slays, so fuck off)
Death Angel - Act III
Metallica - Kill 'Em All

I really need to get some old school Sodom, Destruction, Kreator, Tankard, Sarcofago, Coroner, etc.
 
Man, I dont see how someone could pick Reign in Blood over Show No Mercy. Black magic has one of the best riffs eva
 
Hell Awaits is objectively the best Slayer album, and in my opinion the best Thrash Metal album of all time, since it epitomizes what Thrash Metal is.
 
In no specific order:

Détente - "Recognize No Authority"
Znowhite - "Act Of God"
Hexenhaus - "A Tribute To Insanity"
Mekong Delta - "Mekong Delta" (or "The Music Of Erich Zann")
Coroner - "R.I.P."
Coroner - "Punishment For Decadence"
Voivod - "Killing Technology"
Testament - "The Legacy"
Flotsam & Jetsam - "Doomsday For The Deceiver"
Anacrusis - "Suffering Hour"

A difficult choice, because there are other thrash metal albums I like about as much as some of the ones mentioned above.

np: Sacrilege - "Sight Of The Wise"
 
Slayer - Haunting the Chapel (I wish every day of my life that this had been a full-length)
Slayer - Reign in Blood (I know it's a stock response, but this album really is everything it's cracked up to be)
Dark Angel - Darkness Descends
Kreator - Pleasure to Kill
Metallica - Master of Puppets
Anthrax - Among the Living (GREAT album)
Sodom - In the Sign of Evil & Obsessed by Cruelty
Destruction - Infernal Overkill & Sentence of Death
Sepultura - Arise (don't know if this qualifies as old school or not)
Megadeth - Rust in Peace (again, maybe not old school)

Fuck, those are all such typical responses but they're all such good albums.
 
Infernäl Mäjesty - None Shall Defy
Vio-Lence - Eternal Nightmare
Exodus - Bonded By Blood
Slayer - Hell Awaits
Rigor Mortis - Rigor Mortis
Morbid Saint - Spectrum of Death
Sarcófago - I.N.R.I
Sodom - In the Sign of Evil
Sadus - Swallowed in Black
Sepultura - Schizophrenia

I apologize, english is not my native language. I always thought it was spelled trash.

Or is it so that garbage is trash and the genre is called thrash? If so, then what is the genre named after?
