Oh, I have lots. I could do a thread on that alone. Bloodgood rocks. Bride, Deliverance, White Cross... speaking of which. White Lion, Witesnake, White Zomb... um no, that's defiantly not Glam.
Also there is another little known band Eternal Decision, [ame=http://www.amazon.com/Eternal-Decision/dp/B000CA7QB4/ref=sr_1_5?ie=UTF8&s=music&qid=1229318451&sr=8-5]Amazon.com: Eternal Decision: Eternal Decision: Music[/ame]. Sounds like early Metallica.
I used to have an LP of a British band called Spider that definitely qualifies. I used to love it, but like so many bands they disappeared from my listening list when I switched to CD.
