Sheepscot Valley Chorus presents its annual ever-popular Christmas concert. The featured piece will be Felix Mendelssohn’s Magnificat in D, written when he was 13 yrs old. Even at that young age, Mendelssohn demonstrated a grasp of musical forms which put him in the same ranks as Mozart and Haydn. The concert will also include a varied selection of holiday pieces, with the renowned soprano soloist Mary Sullivan as a special guest. Tickets are $15 for adults, free for students and may be purchased in advance at Sherman’s Bookstore of Boothbay Harbor and Damariscotta, Treats in Wiscasset and at the door.
