Sub-genre of metal that peaked in the 1980s - bands with big hair. They were frequently the smiling-fool kind of thing, so an alternate nickname was "teeth metal". Basically the metal that was the illegitimate child of glam and original heavy metal.
Van Halen, Poison, Motley Crue, Slade, other stuff.
Thanks so much for the metal history lesson & background info!
Never heard before of 'teeth metal' either. I would've categorised those bands as glam.
I've only heard "teeth metal" used in a couple places, in documentary films - never from someone I know.
There were arguments at the time about whether it was actually a kind of metal or just glam, so you're not alone there.
