The two appear as part of New York Philharmonic Offstage, a monthly discussion series. The event is free and open to the public.
Upshaw and the Philharmonic will give the world premiere of Harbison's Milosz Songs for Soprano and Orchestra, set to poems by Nobel Prize-winning poet Czeslaw Milosz, on February 23, 24, and 25.
"Like most of John's music, the songs are each very different from one another, so that in doing them, I feel like I am moving into different rooms of John's mind," Upshaw told Playbill recently. "Over the years his work has evolved into something so concentrated that the musical ideas are direct and very, very clear, as if everything has been cleaned."
