Query: A dated classic

Anyone familiar with the growing oevre of Mahler biographies must have come across Adorno's now-classic work. Long considered the authoritative analysis of Mahler's psyche, next to Bruno Walter's first-hand account, this work has not aged well. Clogged with psychoanalytic jargon - yet strangely devoid of the details of Mahler's brief analysis with Freud himself - and weak on the facts, this book should be eclipsed by the far more informative, objective accounts of Mahler's life that have appeared in recent years. Carr's superb volume comes to mind.
