The crew from Powerhouse Signworks has been out on the streets of downtown Red Bank for a couple of weeks, performing its annual magic trick of giving the district a glittery holiday glaze. The product of their effort debuts on November 27, with the traditional night-after-Thanksgiving Holiday Express concert and tree-lighting, which draws thousands of visitors to Broad and Monmouth Streets. The event is the product of Red Bank RiverCenter, the downtown promotion entity. The Christmas tree and decorations will stay up until mid-January, but the lights will remain in the trees until mid-March.
