Alice Cooper might be metal in some way later on, but his best material (aka Alice Cooper Group) isn't metal to my ears. Thin Lizzy are way more metal sounding than ACDC and Alice Cooper Group combined.
"Emerald" is pretty much the start of epic heavy metal, along with early Kansas.
Thunder and Lightning I guess, but beyond that I can't recall much.
