KitchenWares by Blackstones is hosting a holiday “Cash Mob” on Saturday, December 3 from 10:00 a.m. – 2:00 p.m. in their Back Bay store located at 215 Newbury Street. The cash mobs are part of Constant Contact’s and KitchenWares by Blackstone’s larger efforts to encourage local holiday shoppers to “buy it in your own backyard,” while raising awareness and donations for the Boston-based nonprofit Community Servings.

As a great way to bridge the online and offline experience, cash mobs bring communities and local businesses together, inspiring customers to shop locally. Holiday shoppers are encouraged to visit KitchenWares by Blackstones and participate in their cash mob by bringing a donation for Community Servings while also taking advantage of the prizes, premium giveaways, and store gift cards that will be awarded during the event.

“Cash mobs are a fun way to bring the Back Bay community together while supporting a great cause,” said Co-Owner Jennifer Hill. “While the event is only scheduled for a few hours, we’ll be carrying the spirit of it long after the holiday season as we are committed to supporting other small businesses and the Boston community at large.”

The Aardvark Jazz Orchestra will hold its 44th Annual Christmas Concert at Emmanuel Church.

The concert will feature Mark Harvey’s piece No Walls, an anthem of inclusivity, healing and joy, together with jazz carols and selections from the Duke Ellington/Billy Strayhorn arrangement of Tchaikovsky’s Nutcracker Suite – an exuberant big band take on the perennial classic.

Proceeds will benefit the Refugee Immigration Ministry (RIM), an organization of multiple faiths and cultures that provides support to individuals and families who have been uprooted by violence.

Tickets: $20 at the door. Information: 617-776-8778 or 617-452-3205.
