This is the long lost 2nd original 2nd movement from Gustav Mahler's Symphony No.1. This recording features computer-controlled orchestra instrument samples plus a live real trumpet, played by Trumpeter Dr Julius Eiweck from Austria.
This movement has been rediscovered in 1966. It had been the 2nd movement in the first few performances of Symphony No1, but Mahler discarded it after 1896. Nowadays it is rarely performed, out of respect of Mahler's decision. Latest research shows, however, how the elements and phrases of this movement are frequently quoted in other movements of this symphony.
