Josephine Lang (1815-1880). Her Arabesque is a List C piece. Lang Lang plays it beautifully in a youtube video.

This upload didn't sync video with audio. sorry for that. I don't know why it does that.

Tempo Allegretto and m.m. says 100-108 but I think it's more reflective in nature, and best with lots of rubato. Controlling the separate roles of lead and supporting harmony in the RH is a challenge. It's important to use the time and expression to delineate the phrasing.
Sorry for the little bobble appoggiatura in the final phrase.
