Detailed and thorough biography/study of the great composer. On a narrative level, it is most compelling in the earlier section, given Ligeti's life in Hungary under the two evil totalitarianisms of fascism and communism. After his escape to the West and first international success in the 1960s, the drama mostly went out of his life, which inevitably makes for a less interesting story (but thank heavens so, for Ligeti and music's sake). There are number of interesting biographical topics explored, nevertheless: the slightly fraught business dealings around Kubrick's use of his music, the reasons why the Tempest and Alice operas were never completed, the tortuous attempts to record his complete works, made possible by the generous patronage of a Swiss banker.
Each of the works is given a full exposition. Inevitably, the book relies on quite a lot of technical language in talking about the music, which means that the general reader is at a disadvantage. There are occasions where the author uses more metaphorical means to explicate and bring across the music, and these are very successful. It is enlightening to have Ligeti's musical, literary, scientific and cultural influences so extensively explored.
After the Études, the book gets a little rushed. Although it ends in 2002, before the composer's death in 2006, Ligeti has composed everything he was ever to, which makes the hope of new music in the final paragraphs poignant and forever to be unfulfilled. But the book does bring across strongly how valuable, painstaking, and innovative was Ligeti's contribution to 20th century music.
