Being specific re German Folk Music.
It was mainly hijacked in the 1930s by that lovely Dr Goebells for his own nefarious ends.
Which is why there is little of it left being played nowadays.
Which is also why we formed "Folk against Fascism" in the UK. to counter the BNP doing the same to our identity.
I would love to hear German traditional music too. But, precious few Germans are playing it.
