With her supple, low register voice and on-the-money guitar work, Mary Flower is one of the best blues-based singer/songwriters working today. Classics by Bo Carter, Skip James, and Charlie Patton sit comfortably next to a half-dozen originals. Smart arrangements take advantage of some prominent sidemen (Pat Donohue, Amos Garrett, Paul Geremia, Steve James, Dave Moore, and Geoff Muldaur).
