The program, which repeats tomorrow night, also features works by Virgil Thomson and Aaron Copland.
Summer Sun, Winter Moon, commissioned by the SLSO along with the Louisiana Philharmonic Orchestra and the Kansas City Symphony, was created to commemorate the 200th anniversary of the exploratory expeditions of Meriwether Lewis and William Clark. The work was premiered last month by the Kansas City Symphony.
The narrative in Kapilow's work is partly told from the point of view of the Native Americans Lewis and Clark encountered on their journeys. For these parts of the libretto, Kapilow enlisted the collaboration of Darrell Robes Kipp, a writer and educator from the Blackfeet Tribe in Montana.
The SLSO's performance features soprano Laura Medendorp and baritone Jeffrey Heyl star; Kapilow conducts. Amy Kaiser leads the Saint Louis Symphony Chorus.
Kapilow, currently the Jean L. and Charles V. Rainwater Guest Artist at the SLSO, is a composer and conductor and is frequently heard on National Public Radio's "Performance Today," in a segment called "What Makes it Great." Summer Sun, Winter Moon is one in a cycle of works Kapilow calls Citypieces, works about American historical themes and events, created with community input.
