I've just seen an advertising flier, for some sort of rock group, stuck to a lampost. This 'band' (hate that word in this context!!) was described as (something like), "chaotic indie rockabilly grunge punk". Funny thing is no-one ever seems to object to this sort of absurd categorisation ... but say that you like traditional English folk song and everyone jumps down your throat! I think that this is really because there are people out there who want to replace folk music with rock music. They seem to think that folk music is narrow and elitist whereas rock music is is a broad, all-encompassing 'church'. Actually, I believe that the reverse is true - rock music is a relatively recent, rather narrow form of expression, which has been pushed by marketeers to become all-embracing and is driving out many other musical forms.
