Pianist Christian Blackshaw’s performances can be compared to pilgrimages, being as rare as they are precious. Although a reputed Mozartean, Christian instead brings Romantic sounds to us at his first visit to the Festival: Tchaikovsky and his sensitive evocation of the cycle of seasons on a young Earth, Chopin and his expressive genius, ending with Schubert, whose incomparable Impromptus are the perfect response to the preceding works, as jewels cut to perfect symmetry.
