Etude from the Old Country is a set of variations reaches a high level of rhythmic complexity, polyphonic excitement and virtuosity. It is the longest work in the set and is relentless in its insistent 5/4 meter (this piece was revised later on, but Sarah and Regina are playing the original version).
