The mythology that swirls around Mozart’s Requiem, from its mysterious origins to its posthumous completion, does not dilute the power of the composer’s voice in what has become one of the most recognized classical works of all time. This revered work is paired with Shawn Kirchner’s Songs of Ascent, proudly premiered by the Los Angeles Master Chorale in 2015. A setting of the Psalms sung by pilgrims journeying to Jerusalem, the work has a folk-inflected hopeful tone, delivering a plea for peace and unity and a fervent need to overcome humanity’s divisions.
