Good look at the early New York scene but that's about it, nothing about what was going on in England; about how The Ramones toured there influencing the first British wave of punk. A brief mention of the Sex Pistols and then all of a sudden Nirvana on MTV!! What a load of crap, nothing about the Hardcore movement in America or Britain.
While the whole "Grunge" thing was going on I did not know 1 person that ever considered it "Punk" hence the different label applied to it for the market place to distinguish it from the dangerous "Punk Rockers" similar to the situation with the groups that were lumped together in the 80's as "New Wave".
P.S. I was at one of those underground shows and just to show the degree of separation that we felt from the MTV Grunge thing, in the middle of some bands set when somebody announced that Kurt Cobain blew his head off we all cheered! Looking back (because my musical tastes have widened) I think he was a great musician but it was not Punk!!
