Never been much of a metal guy - closest I get is Finntroll and Melvins (I don't really see melvins as metal myself).
However been scrolling through a few originators on youtube and finding the bits I like and confirming the bits I don't.
Standout for me at the moment is Celtic frost, who are good both then and nowish. Others OK but with some dubious parts are early bathory, venom, and amon amarth. Maybe I'm changing?
Maybe I'll become a butterfly?
