I quite agree with 'A Customer'. This is an excellent introduction to the life and work of Prokofiev. The life story is well told - and what an interesting and ultimately sad story it is, with the composer's return to Stalin's Russia and the difficulties and constraints that brought - and the book is particularly good on accessible and helpful analysis of the music. It is also authoritative. Prokofiev wrote a great deal of music which is hardly ever heard (and indeed in some cases hardly ever heard of here in the West). As a result of this book I have explored some of that music and have found this a fascinating and enriching experience. Jaffe is, in that respect, a very good guide. He fired up my enthusiasm, and I went on to read Simon Morrison's 'Prokofiev : The People's Artist', a stunning (and very readable) work of scholarship, but Jaffe's book is the one to start with, covering as it does the whole of the composer's life and career in what I found to be an engaging and enlightening way. Very warmly recommended.
