The San Francisco Conservatory of Music, Oberlin Conservatory of Music, and the Green Music Center have joined in the creation of the National Brass Ensemble of the United States. The Ensemble consists of 24 brass players and two percussionists from symphony orchestras of Boston, Chicago, Cleveland, Detroit, Los Angeles, New York, Philadelphia and San Francisco. The project will expand to an annual San Francisco Bay Area residency to combine teaching and performances by the nation’s foremost brass players. The ensemble will give its first performances in the Bay Area, June 9-14.
