Merrimack Valley A Cappella will perform during the Mill No 5's week-end holiday Market. See our own affiliated quartets: Accidental Charm and the Derry-Aires! We will bring some treausured winter carols and snazzy, rockin' holiday tunes. This time of year we love to invite the audience to participate in a SING-A-LONG. If you haven't been to Mill No. 5 before, please bring cash and credit for The Market, which features a "farmer's market" style stalls for shopping from local vendors, crafters, and plenty of shops that feature local goods, handmade, foods, books, music, clothing and more. Restuarnats, cafes and a movie theater is also on site.
