Beautiful and refreshing rendition of that Bach aria ...
Enjoyed the Gusli as well ... I too learn something new on this forum most everyday.
Very lovely arrangement and a fascinating and peaceful sound. The Gusli is indeed an interesting instrument with a fascinating history. The relationship to the autoharp, zither and psaltery struck me immediately. Also, it seems that the Balalaika is larger than I had seen. Is this a bass version?
Conducting a search I came upon this somewhat related websiteyou might find interesting;http://balalajka.dk/english/index.html
