George Papavgeris "The fact that I might not recognise a name does not mean he/she is not excellent."

You're absolutely correct. It's my experience that many of the world's great folk musicians are the ones nobody ever hears of.

"Petros is famous indeed, being a member of the Halkias (literally, "Copper") family of Epirus musicians which is well known throughout Greece."

So Greece has its own Copper family! That does it. I'll have to get myself a copy.
