Earlier this year, the Temple Symphony Orchestra was nominated for two Grammy awards. Now the ensemble is preparing to debut a newly commissioned piece by a Grammy-winning composer. In a program that also features Barber's Prayers of Kierkegaard, featuring the combined Temple choirs, and Shostakovich's Ninth Symphony, the Temple Symphony Orchestra will perform the world premiere of Reflections on the Mississippi at the Kimmel Center on Sunday, March 24.
