Some of this stuff is border line metal but for the post part hard rock...
Van Halen
Deep Purple
Led Zeppelin
KISS
Thin Lizzy
Rainbow
AC/DC
Y&T
Alice Cooper
Tesla
Bon Jovi
Guns N Roses
Def Leppard (first two albums are rather metal though despite what the band may tell you)
I am also into alot of hair bands like Ratt, Dokken, Slaughter, Motley Crue, Danger Danger, Winger, Cinderella, etc and they can either be called hard rock or glam metal or whatever so ill count them towards hard rock since they arent heavy metal in the vein of Slayer and Morbid Angel or even Judas Priest and Maiden for that matter.
