Annapolis-based Severn Records has signed the Nighthawks, the Fabulous Thunderbirds, and Mud Morganfield, Muddy Waters's oldest son. Morganfield's CD, Son of the Seventh Son, comes out in March, and new discs by the Hawks and the T-Birds are expected later this year. It's easy to see why Severn will be receiving a "Keeping the Blues Alive Award" from the Blues Music Association. The awards ceremony will be held in Memphis on May 10th. And the Nighthawks play the Creative Alliance on February 24th.
