W.A. Mozart Sonata in D for keyboard 4-hands K. 381 (K. 123a) 

Something unusual ... A Mozart 4-hand sonata in D Major. There is a partial version for harpsichord (K. 123a), and the full sonata that works perfectly well for the instrument. My friend and colleague Valentin Villenave plays the upper part; I was happy to do the "Secondo".
