Founded by conductor and musical director Emily Ray in 1996, Mission Chamber Orchestra of San Jose (MCOSJ) is a volunteer orchestra performing professional quality concerts in the South Bay. The 35 to 50-piece orchestra is known for its innovative programming that surprises and delights its listeners. In May 2011, the San Francisco Classical Voice praised MCOSJ’s performance of Beethoven's Seventh Symphony, calling it "thrilling to hear." MCOSJ features world class artists like Jon Nakamatsu as well as emerging professional soloists. MCOSJ has given the world premieres of more than twenty works and the West Coast or South Bay premieres of many others. MCOSJ caters to a broad audience, featuring classical repertoire and modern works by composers from around the world. Select high school musicians are invited to join the orchestra in many of its concerts.
