Pentatonix

It may not look a lot like Christmas, but it sure does feel like it when Pentatonix comes to town. The a cappella supergroup recently put out its seventh holiday album, The Greatest Christmas Hits, with 23 previously released tracks and eight new tunes for holiday carolers to belt out. Audiences have a chance to get in on the action during Pentatonix’s live shows, when the vocalists invite the crowd to sing along on songs like “Somebody to Love,” “Hallelujah,” and “Mary, Did You Know?”

Saturday 12/9. $55.50 and up, 7pm. John Paul Jones Arena, 295 Massie Rd. johnpauljonesarena.com
