This month's round-up of the latest classical CDs takes in a major new Schubert recording by Mark Padmore and Paul Lewis, a pair of Shostakovich symphonies brought to fresh life in Liverpool under a young Russian conductor from the composer's home-town, a Mahler symphony recorded by the German orchestra that premiered it, a Kipling-inspired satire on artistic epigones by the half-forgotten Charles Koechlin, rare Rossini arias from Joyce DiDonato, a 60th-anniversary box-set from the Bavarian Radio Symphony Orchestra and more.
