Hey Mama’s grand finale in Newmarket: Hey Mama’s story has been short-lived, but the bluesy roots-rockers will be fondly remembered. The Cambridge-based band will play a final farewell show at The Stone Church in Newmarket on Friday, Jan. 21.

Soulful singer Celia Woodsmith and fiery guitarist Avi Salloway started performing together in college several years ago, forming the duo Avi and Celia. They released two CDs and toured across the nation, opening for such legends as Taj Mahal, Leon Russell, and Big Brother and the Holding Company. It was early in 2009 that the pair added drummer Jared Seabrook and bassist Paul Chase to form Hey Mama. The quartet soon released its self-titled debut and has played hundreds of live shows. They unveiled a collection of live and studio recordings called “The Dubl Handi Suite” last fall.

On the heels of that release, the Hey Mama crew is parting ways to focus on individual projects. Salloway will soon travel to Israel and Palestine to work on a peace project and study music. Woodsmith will be spending time with her ill father and pursuing a career in health education services and women’s empowerment.

Hey Mama has been on a Grand Finale tour since November, with the final concert taking place at The Stone Church. They intend to go out rocking.  The show begins at 9 p.m. on Jan. 21 at The Stone Church, 5 Granite St., Newmarket, 603-292-3546. The door charge is $7.

He’s also performed with a lengthy list of other legends, including Bob Dylan, Keith Richards and Bob Weir. His latest CD with Project Percolator, “Pulse,” came out in 2009. The show begins at 8 p.m. on Jan. 21 at York Harbor Inn’s Yorkshire Ballroom, 480 York St., York, Maine, 207-363-5119.
