Query: Great pianist, poor presentation

While it is a pleasure to have another Arrau performance of Beethoven's 5th piano concerto, the presentation is disappointing. First of all there are about 40 minutes introduction, with a montage of interviews, rehearsals and so on, with a devastating commentary. Afterwards you get a hum-drum performance with a rather mediocre orchestra, tiny sound and not much of a concept. But what is really annoying about this disc? Well, there's a gap between sound and image, a gap of less than a second, to be sure, but enough for a distraction from the presentation. Finally I chose to switch off my tv and preferred to listen only.
