My basic point is that although there were many bands that were very similar(Cinderella and Britny Fox, anyone?) there were four in particular that got screwed over by the grunge explosion by being dismissed as "one of those damned hair bands". Extreme, Skid Row, Tesla and Mr. Big all had more talent than any grunge or hair band. They were lumped in with that genre but weren't really like it. None of these were glam at all, neither in look, nor in sound.
I also dispute a point made earlier that bands such as Poison got cheesier as they went along. It was really the opposite. Poison started off with "Look What The Cat Dragged In" in 1986, absolutly smothered in makeup and hair-spray. As time went on, they ditched that image and weren't really glam by the time "Flesh and Blood", the album with 'Unskinny Bop' came out in 1990. The rest of the album made an attempt to be more serious than previous efforts but it was all negated by 'Unskinny Bop'.
From the looks of it, my warning not to call any rock band the came out in the 80's or 1990/91(thank you, though, Superfly
) was ignored for the most part.
PS: The only true hair bands:
Winger (Beavis and Butthead didn't help)
The big ones, namely Guns 'N Roses, Bon Jovi, Def Leppard and Mötley Crüe don't belong in that category either.
