I saw a group called Harmonia at the Philadelphia folk festival last year. They play a mix of tunes from Hungary,Romania,Ukrane,Slovakia and the Balkans. I seem to recall they were based in Millwaukee? Not sure though.Band members are,Walt Mahovlich,accordian & clarenet.
Alexander Fedoriouk,cimbalom.
Marko Dreher,voilin.
Andrei Pidkivka,Panflute,sopilka.
Adam Good,bass.
Beata Begeniova, vocals.
A very energetic band.
Unfortunately,that's all the info they provided in the PFF program & I couldn't find this particular Harmonia when I did a search.
Good luck,Ron.
