The Hopkinton Center for the Arts presents its Sunday Jazz Jam on Sunday, Dec. 8, from 11 a.m.-1 p.m. An hour-long concert will be held in the barn loft featuring the MetroWest Jazz Project, a collaboration of jazz musicians playing acoustic contemporary jazz featuring the unique sound of the vibraphone. A public jam session afterward welcomes amateurs and professionals of all ages and talents. This is a free event, but donations are appreciated. For more information, visit hopartscenter.org/events.
