It was the artistic equivalent of raising the Titanic...When Gustav Mahler died, he left a vast final symphony tantalisingly incomplete. Five decades later, musicologist Deryck Cooke did the impossible and brought it to life, uncovering a lost masterpiece filled with puzzles and allusions - music in which cries of love and cries of pain resolve in music of shattering honesty and heartbreaking power. This is art that explores the great questions of life, and tonight, popular guest conductor Antony Hermus returns to guide us to the heart of Mahler’s final musical testament. He prefaces it with something unfamiliar, but wonderfully appropriate - a haunted, restless meditation on loss, Mahler and mortality by the remarkable Dutch composer Willem Jeths.
