Of all Mozart's twenty-seven concertos, No. 20 remains particularly memorable for the attention that it attracted from other composers/pianists. Beethoven often performed it and even composed his own solo cadenzas for it. Mozart had not written his own cadenzas but had only improvised them at performances. Brahms, too, knew the work, and composed cadenzas. These are just two of the interpretations that feature on this disc, performed by the pianist Michael Rische.
