This disc of keyboard music for four hands has a claim to our attention beyond the mere excellence of the playing. Goldstone and Clemmow draw on their own reflections and those of others for their programme, the indefatigable Goldstone offering his realisation of an abandoned Sonata in B flat major for two pianos, a substantial 21–minute work and an enterprise that occupied him intermittently over eight years. It’s well worth hearing and provides a much–needed companion for the great K. 448, Mozart’s only completed work for two pianos, which concludes the disc in effusive high spirits. Goldstone also contributes a two-piano version of the Adagio and Rondo for glass harmonica (he and his wife drawing magical musical box sounds from their two grands). The two other works are Busoni’s faithful 1923 arrangement of the Overture to The Magic Flute, and the Sonata in G, K283, one of four Mozart sonatas to which Grieg added amusing but stylistically anachronistic and ultimately redundant second piano parts. Lovely disc, complemented by Goldstone’s notes.
