A century after his death, Gustav Mahler is the most important composer of modern times. Displacing Beethoven as a box-office draw, heard in Hollywood films and on state occasions, his music inspires particular devotion. Some believe it helps heal emotional wounds, others find intellectual fascination in its contradictory meanings, and many feel that the music captures the yearnings and anxieties of our post-industrial society. In this highly original account of the composer''s life and work, Norman Lebrecht explores the Mahler Effect, asking why Mahler''s music has become the soundtrack to our twenty-first-century lives.
