Filling in for Bostridge will be Stanford Olsen. A winner of the 1986 Metropolitan Opera National Council Auditions and the 1989 Naumburg Award, Olsen has sung in concert with dozens of prominent orchestras, including (among others) the Boston, San Francisco, Chicago and Cincinnati Symphonies and the New York Philharmonic; he has performed on stage at La Scala, the Deutsche Oper Berlin, Paris's Th_ê¢tre du Chê¢telet, the Australian Opera, La Monnaie in Brussels, San Francisco Opera, Houston Grand Opera, and Santa Fe Opera (among others) — not to mention the Metropolitan Opera, where he made his debut on one hour's notice during the run of I Puritani in which Joan Sutherland gave her farewell performances.

Olsen will join Orpheus and horn soloist Stewart Rose for Benjamin Britten's Serenade for Tenor, Horn and Strings. Also on the program will be Bohuslav Martinu's rarely-heard Serenade for Chamber Orchestra and Mozart's "Posthorn" Serenade.
