“A good performance of the fifth symphony is a life-changing experience. The fantastic final movement almost forces you to hold your breath,” is how Herbert von Karajan described Gustav Mahler’s masterpiece. Although it received rather a cool reception in its own day, the symphony has since become Mahler’s most performed piece. The Adagietto fourth movement, which was used in the film Death in Venice, still brings a tear to the eye. “Harmonica” for tuba and orchestra by Helmut Lachenmann, a living legend of German concert music, is his most striking concerto.
