The Oslo Philharmonic under its conductor Mariss Jansons is now one of Europe's top orchestras. Their concert tonight from London's Royal Albert Hall begins with a bizarre work by Russian composer Alfred Schnittke. He calls it (Not) a Midsummer Night's Dream and in it a tune which could be by Schubert is taken on a nightmarish journey. Schnittke says of this tune: "I didn't borrow it, I faked it!"
