In an English folk club, you could probably get away with a recital on the Albanian nose flute, if you did it well. Check out a marvellous duo from the 1970's called Cosmotheka - named after a Victorian London music hall where Dan Leno made his debut.

Cosmotheka performed the kind of material you describe and did it so masterfully that they had few critics. They were simply one of the most entertaining acts I have ever seen. Ian Campbell knows a thing or two about folk music, and he described them to me as the only really new addition contributing something of lasting worth in the 1970's.

They were stunningly different from anything that had been seen before.
