A number of new recordings this week: The Monteverdi Choir in Bach with the English Baroque Soloists and in Beethoven with Orchestre Révolutionnaire; Simon Trpčeski and the RLPO in Rachmaninov; the Choir of St John's College Cambridge in Howells; the London Philharmonic and the London Symphony each in Mahler symphonies; and Nelson Freire in Chopin Nocturnes. Yet despite the stiff competition, no entry can topple André Rieu and "Forever Vienna", which holds on to the top spot for another week.
