'Mozart - it's always been Mozart. There are endless composers whom I admire, but I couldn't get along without Mozart.' If Andr� Previn's name is often identified with large-scale works of the 19th and 20th centuries, Mozart remained close to his heart. Partnered by the London Symphony Orchestra, of which he was principal conductor from 1968-1979, he is soloist in the moody 'Piano Concerto 20, K466', a work much admired by the young Beethoven. In the more consistently sunny 'Concerto for Two Pianos, K365', Previn and the LSO are joined by Radu Lupu - an interpreter of proverbial refinement.
