Under the direction of Jo-Michael Scheibe, the USC Thornton Chamber Singers is the premiere choral ensemble at USC. This past November, the Chamber Singers were joined by the USC Thornton Concert Choir and Symphony in a magnificent performance of J.S. Bach’s Mass in B Minor under the direction of Maestro Helmuth Rilling. Earlier this year, members of the Chambers Singers and Concert Choir joined Andrea Bocelli in his performance of “My Christmas” for PBS. Among its other recent achievements, the ensemble gave the keynote performance at the 2005 national conference of the American Choral Directors Association at Walt Disney Concert Hall. In 2002, the Chamber Singers won the Grand Prix of a prestigious international choral competition in Tours, France. The Chamber Singers, in conjunction with the USC Thornton Concert Choir, has performed in recent years with the Los Angeles Chamber Orchestra and the Los Angeles Philharmonic. They perform regularly in concert halls around the country and around the world: they had tours of Korea (1994), Poland (1997) and China (2006).
