Portland's 19-piece big band returns to the State Theatre for its annual holiday blowout — a show that's become a Maine tradition. The full horn section and a rotating cast of Maine's best guest vocalists rework Christmas classics and offbeat holiday deep cuts alike, with stops at Rat Pack swing, funk, Afro-Cuban fire and straight-up rock. Part singalong, part family reunion, all horns. Expect a packed stage, an even more packed house, and a night that sends everyone home with the spirit of Christmas.
