CHILDREN’S PLAY: As the theme of his fourth annual Santa Barbara Chamber Music Festival (June 16-18 at the First Congregational Church), founder and music director Daniel Kepl has rather shrewdly chosen the title Immigrant Nation, and is featuring composers who are the “children and children’s children of immigrants to this country from all over the world.” They include Aaron Copland, George Gershwin, Robert Muczynski, Pierre Jalbert, Norman Dello Joio, Gabriella Frank, Joan Tower, Richard Pearson Thomas, Richard Lavenda, Samuel Barber, Arthur Foote, Ingolf Dahl, and Santa Barbara composer Leslie Hogan.
