"Russian Folk Song-Barynya(The Lady)"-with variations played on electronic bayan by Anatoly Belyayev
This is from an 1969 album on the Melodya label. The interesting thing is that Anatoly took something like a Cordovox & put bayan reeds in it & the result is quite amazing. You'll enjoy his exciting arrangement of this popular Russian folk song full of daring originality & even a bit of Russian "Rap."
