The Boston Camerata gets off to an early start on Aug. 10 with “Verdant Grove,” a gathering of early-American song. The centerpiece in fall is “The Play of Daniel,” an exploration of the biblical hero in music from the Middle Ages (Nov. 21 and 23). This year’s holiday offering is “An American Christmas,” one of its most popular programs (Dec. 18-20). The group has a residency at MIT, with a March 6 concert, and reprises its interfaith program, “A Sacred Bridge,” on March 29.
