'Are Collected Letters a superior form of biography? When as numerous and meticulously edited as these of Gustav Mahler, when they provide a time capsule ride back to the last days of the Austro-Hungarian Empire, the answer must be yes... This remarkable book is unputdownable, even for a non-Mahlerite'. Literary Review 'A vivid and telling portrayal of Mahler's personality in his voice.' Times Literary Supplement 'The letters are linked by a commentary that makes the volume both an easy and gripping read... There is passion in this book to scald the hand.' Sunday Times
