None of those bands is a "metal" band IMO... Rock yeah, maybe even "hard rock," but metal??? Slayer, Dark Throne, Deicide, Cannibal Corpse, Morbid Angel, etc were the metal bands of the 90's.
None metal?! Uh ...
Huh?! Scorpions (most of the material) is metal; Ozzy is metal; Van Halen's first six is metal; AC/DC is ... mostly hard rock (but is very "metal" in its whole "thing"); Maiden is METAL (one of the style's very pillars); Metallica is metal (only the first four releases matter, for me, and it's one of the Big Four of '80s thrash); Anthrax is metal (one of the '80s' Big Four of thrash); Queensryche is metal (at least up until Empire, and then again after Geoff was replaced, on the last two); and Priest IS METAL (arguably one of the genre's very greatest architects).
And just so you know, I'm 45, and I have been listening faithfully to hard rock and heavy metal since I was 12. Own the entire discographies from every band you mention. And any available DVDs.
I buy, on average, between five and 10 CDs, each and every week.
I have a collection of extreme metal (thrash, death, black, etc.) that numbers in the thousands.
I adore some of the harshest, most extreme and vicious bands under the very wide (and inclusive) umbrella known as heavy metal.
For you to state bands like Priest, Maiden and Anthrax aren't metal is
pure nonsense/a
major attempt to appear contemporarily tr00.
Or you're just new to the music. As in, been a fan for less than 10 years.
I hate those who always try to move metal's lineage timeline further forward along as time passes. It's disrespectful to the style and shows an unwillingness to embrace the inherent sturdiness of this very progressive and sturdy musical form.
