Gramophone - The musician and the score

Mozart’s First Piano Quartet, K478. 

“Of course, we know the story about Mozart losing the publisher’s commission for this quartet because it was too difficult for amateurs,” muses Dego, “and it’s true - but the difficulty is also musical. You need to understand what it’s saying here, and create all the different voices. It isn’t one of the sight-readable things that were fashionable at that time. It has all the theatre, it has all of Mozart, it’s extraordinary.”
