Opinion in all parts of the world would agree that Rachmaninoff is the most complete of living masters of the instrument; his technique is comprehensive, and he is, of course, musical to his bone's marrow. Most important of all, he is a composer, and for this reason he is able to approach a work as none of his pianist contemporaries can approach one - that is, from the inside, as an organic and felt creative process.
