This November, Stefan joins forces with frequent collaborator, pianist Jeremy Denk, for a tour of the complete sonatas of Charles Ives. They will perform the cycle at several venues, including at New York City's 92nd St Y and at the Philadelphia Chamber Music Society. Prior to the Ives tour, Stefan returns to Amsterdam's venerated Concertgebouw with the Netherlands Philharmonic and makes his Tokyo Symphony debut under conductor Krzysztof Urbanski.
