Meh Punk is DEAD! Muwahaha. Ahem.
On a serious note I think Punk came about because folks were being spoon fed 'trends'. Unlike any other genre I think Punk came about in a kind of rebellious way? People were sick of the little sheepies in society. Most people feel it all kicked off with the Pistols, but I think they made it into a bit of a novelty in some ways.
So what is Punk? It's individuality, brashness, balls and a helluva choon.
Happy now?
