New England rock band The Gallery will be performing at Rockwood Music Hall on Dec. 21. The group, comprised of Brendan Cooney, Ryan Cooney, Dave Mozdzanowski and Ben Lozano, are trying to build up some hype in anticipation of their next album’s release in early 2013. The Gallery set out on their first national tour in 2009, and haven’t looked back since. Warren Huart has been the group’s recording producer, and brings an impressive resumé that includes work with Aerosmith and The Fray. The concert will be free, although donations are encouraged.
