“Where exactly does speed metal stop and thrash begin? It’s a question that pops into my head nearly every time I listen to a speed metal album, but I’ve never come up with an answer that satisfies me. I’ve searched online and found different explanations: “thrash has punk in it, speed doesn’t” or “thrash has harsh vocals, speed doesn’t” or “speed metal is essentially sped-up traditional metal while thrash is extreme metal” or “thrash uses the low E-string to build riffs” or “blah, blah, blah.” There’s some truth to all of these, but I still have no idea how to describe the difference in a definitive way.” Fine and fast lines.
