Having recently heard Alexei Lubimov excelling in John Cage, it was fascinating to hear the Russian pianist bringing the same clarity and penetration to Mozart. He has recorded the composer before with compatriot Yury Martynov, but this new collection has an unbeatable elan and drive. Some may find the glorious Sonata in D for two pianos too driven, but the pair capture the exuberance of the Larghetto and Allegro in Robert Levin's splendid completion, and the rarity here is an arrangement for two pianos of the lovely Piano Quartet in E flat by Johann Pratsch, adding tasteful embellishments and flourishes.
