His singing has taken him to many festivals and venues, including Tanglewood, Concertgebouw, Théâtre des Champs-Élysées, Lincoln Center, Kennedy Center, the Metropolitan Museum of Art, Washington National Cathedral, and the early music festivals of Boston, San Francisco, Vancouver, Houston, Tucson, Washington DC, and Madison, as well as the Regensburg Tage Alter Musik.
