If you are a Lisztomaniac, this is for you. It is a book that is very difficult to put down. Liszt's life reads better than a novel, and Walker's narrative flows superbly. He has investigated every biographical avenue and brings the Weimar of the 1800's to life.
On the negative side: There are copious footnotes, which often stray off the subject, whilst others belong to the main text from which they divert. As the book is meant to be a work of scholarship, the amount of opinion and speculation which peppers the book is also rather annoying. One has to be very cautious in separating Walker's own views from the first-class academic research that he has done.
Nonetheless as this book covers the most prolific period of the composer's life, you can do no better than read Walker's account to dicover just who Liszt was, his importance to musical history and the enigma of the man himself.
