Mozart's Concerto in c K491, with Cadenzas by Zacharias, edited by Christoph Wolff and Christian Zacharias, and piano II (orchestra) by Roland Erben. The work was completed in Vienna on 24.3.1786. The solo piano part is identical in all respects to the text of the original sources. The piano reduction of the orchestral accompaniment (Piano II) had been made as consistent as possible with the original score as regards dynamics and articulation.
