I never really got into a lot of the US metal scene. I don’t do the brutal death stuff like Deicide and all them or the post nu metal stuff ala Lamb of God and all those bands with full sentences as band names that seems to be really prevalent. The US does have some real gems though. Agalloch, Iced Earth, Symphony X, etc. Plus the obvious legends and the better examples of hair metal. Oh the hair metal.
I think that rather than being its own scene I’d argue that the metal coming out of Scandinavia is just the cream of the crop of the larger European metal scene. It’s not as if they are all producing some sort of homogenous output. You want black metal you look to Norway. You want death metal you go Sweden. You want folk influenced metal or power metal you’re looking for Finland. Germany obviously has their industrial stuff as well as the whole medieval metal scene. Etc. There‘s obviously significant crossover as well as a decent number of American bands in these styles.
I guess the point I‘m making now (I don’t know that I was when I started) is that I don’t know that the modern UK scene is particularly distinct from that wider scene. Maybe it is? Either way, to me England is ground zero for heavy metal. NWOBHM basically kicked off everything around the world. Of course there’s Black Sabbath. One could argue that Ritchie Blackmore and Dio are as important to the foundational sound as Sabbath. And let’s not forget Iron Maiden. Easily as influential as Metallica, nearly all melodic metal is in their debt.
Wait. What was I talking about? Everything I just said might’ve been nonsense.
