By the way, I was never a big fan of hair bands or power ballads, but there was an awesome documentary on VH-1 about the history of metal...it started with Black Sabbath in the late 70s and went all the way up to modern marylin manson. But it was great watching all the old hair bands get out of control.
Hair bands like Crue, Twisted Sister, Scorpions, Warrant, Ratt were all on and showed how bands like Metallica actually were struggling to belong because with the mainstream bands...that is, if your band wanted to sell records, you had to dress like a woman and have at least one power ballad on your album. Anyway it was a great documentary!
And to this day, it still amazes me how much the beatles influence even modern music...after all, they were the first "rock" group to wear their hair long!
