Probably not all of them, but some "quality control" would haven been of help .... btw it is particularly ironic that he accused Bruckner of this (and was part of a movement which destroyed Bruckner's career during his lifetime) .....
Thnx .... I'm interested in his career until the late 60's .... thereafter not so much .... so also books about his life will have always have an ambivalent reader with me ....
