During the 2021/22 season he sings 4th Jew in Salome, Ossip, the Sexton, in a new production of Rimsky-Korsakov's Die Nacht vor Weihnachten / The Night Before Christmas and Desiré and Goro in two more new productions: Giordano's Fedora and Madama Butterfly. Recent roles for the company have included Antinous (Fauré's Pénélope), the Rebel (Das geheime Königreich / The Secret Kingdom), Oedipus (Stravinsky's Oedipus Rex), Leukippos and Apollo (Daphne), the Captain (Wozzeck), Trimalchio (Maderna's Satyricon), the Witch (Hänsel und Gretel), Pedrillo (Die Entführung aus dem Serail), Matteo (Arabella) and the Shabby Man (Lady Macbeth von Mzensk). Roles in earlier seasons included Lord Arturo Bucklaw (Lucia di Lammermoor), the title role in Zemlinsky's Der Zwerg / The Dwarf, Kimmo (Sallinen's Kullervo) and Mozart (Rimski-Korsakov's Mozart und Salieri). He enjoyed great success singing Walter in a new production of Weinberg's Die Passagierin / The (female) Passenger in Frankfurt, which went on tour to the Festwochen in Vienna – a role this American tenor then performed at the Israeli Opera in Tel Aviv.
