Ten favorite 80's (hair)/metal bands... wow that's hard to do, I loved so many more than those.
Bon Jovi
Ratt
Poison
Motley Crue
Cinderella
Skid Row (they opened for EVERYONE, and still do)
Whitesnake
Def Leppard
Queensryche
Metallica
I guess that list of ten will have to do.. I can't really order them though aside from saying that Metallica and Queensryche made the biggest lasting impression on me... then again, I still go see most of these guys anytime they tour, so.. yeah. Great stuff!
*Honorable mentions to Dokken and Stryper who I also had in heavy rotation at the time, and Tesla who was another constant show opener back in the day -- gotta love "Signs".
edit -- oh man, Scorpions is another one for sure.
edit 2 -- GnR crept in late in the whole 80s scene, didn't they? If not early 90s? But they came in hard and stayed there. Once I heard "Welcome to the Jungle" on MTV during the world premier, I was hooked.
