Alexander Borodin was actually trained as a chemist and physician and spent a good deal of his time promoting womens' issues, much to the consternation of his fellow composers who wound up finishing up much of his work after his sudden death at the age of 53. The opera Prince Igor is possibly his greatest and boldest work with many beautiful melodies coming forth, especially the Chorus and Dance of the Polovetsain Maidens from Act II. The music has an mysterious Eastern sound which is very captivating.
There is nothing like this written for the Euphonium and Mr. Sauer's arrangement is wonderful.
This work is about 7 minutes in length for advanced performers.
