The Mad River Chorale, a non-auditioned community chorus conducted by Arthur Zorn, presents an exciting and varied program of holiday music both sacred and secular, quiet and rousing, classical and contemporary. The fifty or so singers are accompanied by two pianists, a percussionist, and the Inora Brass, a quintet of northcountry musicians with over 100 years of experience, two of them Grammy Award winners.  The audience will, as always, join the chorale for some of the songs.
