Spend an afternoon luxuriating in a program that includes Bach’s soulful Cantata 2: Ach Gott vom Himmel sieh darein (Ah God, look down from Heaven) and six of the most beloved and enduring arias of J. S. Bach drawn from the entire lifelong output of the master, including “Erbarme dich,” an alto aria from St. Matthew Passion; “Komm in mein Herzenshaus,” a soprano solo from Cantata 80; “Agnus Dei,” an alto solo from the B Minor Mass; “Ach mein sinn,” a tenor aria from St. John Passion; “Ihr Menschen, rühmet,” a tenor solo from Cantata 167; and “Wann komst du, mein Heil,” a soprano and brass duet from Cantata 140.
