Here's a site with some anecdotal info on glam rock and the changes that music went through related through the stars of the time.
I know it is mainly 70's, but I think it has some interesting stories in there and shows how "pop" music was evolving and probably paving the way for the diverse range of music that was the 80's.
also some of the bands mentioned were still around in the 80's
