yeah, but 80's metal definitely had it's talented end too....the whole hair band thing was basically metal for the masses, commercialized & glamed up, but bands like Metallica & Quensryche & Dream Theater, that stuff was cool...
the 3 bands u mention are definately more serious musicians. the bands I'm thinking of were in it for the women, the drugs, and the hair spray.
for real. metallica and dream theater are some of the most talented musicians i've ever heard. and dream theater has amazing stamina with their 13+ min. songs.
