This, Anonymous 4's final recording, is a break from their usual "early music" periods and locations; it presents American music, religious in nature, from the 18th and 19th centuries. And it's absolutely beautiful from start to finish. Their normal, exquisite technique and purity here blend to sound the way we imagined the ladies' choir in church meetings in America past might have sounded: sweet, sincere, and with harmonies recognizable yet somehow fresh. Some of the songs begin with the women singing "fa, so la" exercises, which was called "shape note" singing because some places taught singing with notes as shapes--circle, rectangle, diamond, triangle. But it's the music that counts, and there are treasures here. They include two versions of "Amazing Grace," one familiar, one with an unusual melody and a piece called "Blooming Vale" which is as sophisticated as anything on their previous albums. "Shall We Gather at the River" is performed with a clarity and loveliness that makes us forget that it's normally sung as background to movies about the Great Depression. The foursome sometimes sing in rich harmonies and occasionally alone or in pairs or trios. This is glorious Americana and highly recommended. --Robert Levine
