The difference, by ear

Technical death metal is the direct descendant, and several of these musicians made both - Atheist appear on this list and on that one.

Technical death metal is growled or screamed where technical thrash is shouted, at much the same pace, around 160 to 260 bpm. To hear the difference, play Voivod next to Death. They share a root in heavy metal, and technical thrash came first, by three years. United States and Canada appear in the origins of both.
