I have seen many 'What is folk' threads on The Mudcat but I cannot remember seeing too many 'What is blues' ones. Maybe on other sites, a furious debate goes on about this subject but I think not to the extent that we seem to here, about folk. Why might that be?
You look at a music that had its beginnings in a US, black culture and is now championed by just about everyone, except, possibly now the black culture that spawned it. It produced a strange effect where the originators or the music in America, were to influence performers in Europe (the UK especially), who in turn influenced a whole new generation of (mainly white) American ones. I am thinking of people like Stevie Ray Vaughan, who in turn went on the inspire even more.
The music has gone through a lot of changes but still can be pretty easily recognised and appears to be in a pretty healthy condition?
Do the disputes and definitions that divide folk music not exist with the blues?
If they do not, could it be that blues music in firmly in the hands of those that just get on, make and listen to it, rather than at the mercy of collectors, scholars and experts, who feel they have to categorise, and to constantly defend and preserve some idea of purity?
And yes, this could be seen as another means of starting yet another 'What is folk' thread, but do not most of our discussions tend to end up as that anyway?
