One selection has been announced: excerpts from George Balanchine's Liebeslieder Waltzer. Russell and Stowell's sons acquired the rights from the George Balanchine Trust for a one-time performance of the work as a tribute to their parents, who have performed the work many times between them.

Their son Christopher Stowell, artistic director of Oregon Ballet Theatre, is acting as artistic advisor for the evening's program, which will be followed by a Champagne reception.

Peter Boal, a dancer with the New York City Ballet, will take over the position of PNB's artistic director in the fall.
