Under the leadership of new artistic director Gavin Thrasher, the chorus of nearly 300 voices will perform holiday classics and unique seasonal offerings with a special twist, some of which have been part of the NYCGMC’s annual holiday concert tradition since the chorus’s founding 40 years ago. Selections include: “Christmas (Baby Please Come Home),” “Joy to the World,” “Hanukkah in Santa Monica,” “Stopping by the Woods on a Snowy Evening,” “Put a Little Holiday in Your Heart,” Barbra Streisand’s “Jingle Bells,” Sara Bareilles’s “Love is Christmas,” plus more.
