I think big hair and MTV go together; I hadn't really made the connection until a few posts ago (well, look, it's not like I spend too much time thinking about glam bands). And there reason that most of these bands, while here and there delivered a catchy hook, or in some cases had real talent, don't make me want to play the drums again is because...it's all too visual, too commercial, too MTV. MTV is disgusting, and what it does to good music -- my opinion, my experience -- is, at best, distracts from it.
I recall that early video by Michael Nesmith, "the talented Monkee," and it was cool and novel but it wasn't big hair and bs. The MTV thing is top 40 TV, and top 40 radio is hard enough to endure for long.
Truthfully, though, a lot of glam rock bands had a lot of songs and videos on MTV that were never Top 40 hits...
Dokken’s “In My Dreams” - great song, but only reached #79 on the pop charts, for example.
