CAMBRIDGE — The Sacred Shakers haven’t been much of a going concern lately, a situation abetted by the fact that a number of the group’s members no longer live in the Boston area. So it was a treat to see them regroup for a few shows recently, and even more of a pleasure to see them congregate Thursday for a show being recorded for an upcoming CD.

If the Shakers were rusty, it hardly showed. A rehearsal show two nights earlier helped to shake that, and a “do-over” set that followed two hours of music allowed them second takes on songs they judged not up to snuff the first time through. There were a couple of false starts during the main set’s two hours, too. But those were impositions of the recording process. They sounded in vintage form.
