AUBURN, Maine — Late notice, but do join Bald Hill this evening for three hours of live and lively entertainment here at the Side By Each Brewing Co. BH, those surprisingly hep purveyors of newgrass, folk rock and Americana, will be joined on stage by members of the Amiable Critters — the one-time Norwalk, Connecticut-based super group — in addition to other special guests, assorted former Bald Hill collaborators, several farm animals and a cardboard cutout of Bobby Goldsboro.

Curtain is 6 p.m., leaving plenty of time for music, food, SBE’s signature beer (try the Kuriro rice lager) and related frivolities. Don’t miss it!

The Critters were, in fact, the DeTroy family band made famous throughout key-but-limited portions of the Nutmeg State by their multi-part harmonies, square jaws and hearty German stock. Ben DeTroy remains the mandolin and fiddler for Bald Hill, of course. Tonight he is reunited with brothers Tom, on vocals, and Matt on keyboards. Also on hand this evening are former Bald Hill drummer Kim Chasse and serial in-sitting crooner Ted McHugh.

“It’s going to be some beautiful, sonorous chaos up there tonight,” Ben DeTroy explained the night before. “A bit like The Last Waltz, only without the heavy drug use. Or Dylan.”
