This album by the all-female medieval vocal ensemble
Anonymous 4 resembles one of its earlier releases,
American Angels. Both focus on American music, and specifically include the tradition known as shape-note hymnody -- it was (and is) printed with noteheads in different shapes associated with solmization (or, in the parlance of its practitioners, "fasola") syllables.
Gloryland delves a bit more into later forms of white gospel music, and also includes more secular folk songs associated with the launch of a new folk duo by two of the ensemble's members. But the biggest difference between the two releases is that
Gloryland features instrumental contributions by progressive bluegrass musicians
Darol Anger and
Mike Marshall. They accompany the singers and perform interludes and a few whole pieces by themselves on fiddle and mandolin, also using such novelties as a baritone violin and mandocello.
