Eric Bibb Sisters & Brothers

As its title implies, this is a spiritually based collaboration from three distinct – even disparate – yet surprisingly harmonious voices. Mostly, but not entirely acoustic, the trio of rootsy singers trade lead vocals on smooth jazz/blues ("Bessie's Dream"), folk-blues ("Good Stuff"), Delta blues ("Rolling Log"), gospel (an a cappella version of Sister Rosetta Tharpe's "Rock Daniel"), and combinations of those genres. On paper it sounds scattershot, but in actuality this is a thoughtfully paced combination of styles, united by three affecting voices. Eric Bibb's smoother Keb' Mo' approach meshes surprisingly well with Rory Block's more penetrating Delta croon and Maria Muldaur's sassy, sexy, throaty growl.
