Son, i think you seem to have misunderstood me.
That same Wikipedia article, go up to the first sentence where it says they are a THRASH METAL BAND. That is what i am saying. THAT THEY ARE A THRASH METAL BAND. YOU TRIED TO IMPLY THAT THEY WERE A DEATH METAL BAND. I voted for death metal as secondary for a few of their albums too(along with a bunch of other 80's thrash albums, does that make them DM too?), but that still does not change the FACT that they are thrash metal albums. Are Motorhead and Venom thrash? Is early Death(as thrashy as it is) thrash?
Anyone that thinks Sepultura were a death metal bad needs to turn their card in ASAP.
oh and death/thrash still falls mainly under the thrash umbrella, but im sure i didnt need to tell you that.
