This book makes a case for the power of music as culture's memory, an art form uniquely capable of carrying forward meaning from the past. Eichler shows how four towering composers - Richard Strauss, Arnold Schoenberg, Benjamin Britten and Dmitri Shostakovich - lived through the era of the Second World War and the Holocaust and later transformed their experiences into deeply moving works of music, scores that carry forward the echoes of lost time.
