It all depends on what you yourself think what metal is. And what it boils down to is what started metal. Its the bands like Led Zeppelin, Deep Purple, and of course Black Sabbath. While nowadays they aren't really considered metal. But they were. And as you keep going forward in time you can see what has evolved from those bands. Those bands all developed from blues and classical. And you cans still see all of those elements in todays metal. To me personally it has to be bleusy to be metal. I think for it to be metal is has to have elements of everything previous pioneers have done to pave the way for metal. Metal is a direct descendant of blues in my opinion. And from that developed great bands such as the previously mentioned. And from that came great bands like Judas Priest, Iron Maiden etc. Then thrash metal came thanks to the likes of Metallica. It all have evolved and does sound alot differant from back in the day. But remaining the same roots has made metal what it today.
