Today, I listened to your dad playing the Brahms' Double Concerto with Menuhin under the conduction of Casals. What a great interpreter he was! It is a 1969 recording. Just amazing! It seems to me that Mr. Parnas perfectly understood what Casals wanted to do with this work. There is an incredible communication between them. Best regards from Chile!
A beautiful documentary of a great musician and a great music festival. The "Haffner" rehearsal sequences are especially interesting for what they reveal of Casal's musicianship. At one point, for instance, he says, you cannot do forte and piano subito, you must first have a diminuendo after the forte, even though it's not marked in the score --- for if you play it as written, what Mozart wrote will not be heard. This is "authentic" music-making in the true sense.
