Metallica used to be OG Thrash Metal. They aren't as Thrash anymore, but that doesn't mean they aren't still really solid music. I used to have major issues with them for no real reason, but I'm finally over that, ya know? It's all good music even if it isn't exactly what I want to hear from them.
Clutch video though, it's got that nifty spinning room illusion going on that everybody loves and the song itself is good to go with it. Like yo, plain old Rock music is a lot of fun that I feel like I trash it a lot. It's not bad at all, I just don't listen to it that much.
No Metallica fanboys, I don't classify them as Rock, it was just an example.
