Level IV choristers are increasingly invited to participate in professional-level performance opportunities, and enthusiasm for and dedication to these opportunities is part of full participation in Level IV. Level IV appears annually in productions of the San Francisco Opera and will, for a second year in a row during the 2018-2019 Season, perform as the chorus and in the title role of Little Prince for Opera Parallele's production of Rachel Portman's "The Little Prince". Level IV has also recently performed with Kronos Quartet for KRONOS FESTIVAL 2018 and at the Kennedy Center with The Knights for SHIFT: A Festival of American Orchestras. Many of these singers performed in the San Francisco Symphony's “An American Journey with Charles Ives," which earned a GRAMMY Award.
