The Cleveland Orchestra and Chorus, along with assorted guest choruses, team up every year at this time for an annual offering of music for the season, including singalongs and a very special guest. The concerts take place in the "yuletide splendor of Severance Hall," a gem of a space aglow with festive decor. Tonight's performance is at 7:30 p.m. The concert series continues through Sunday. Consult the orchestra website for more info. (Niesel)
