This is the blues trio's fourth album, which finds the band recharging their mojo with an expansive array of material. They're still tending the roots, like on the incantatory version of R.L. Burnside's "Going Down South." But they uncover a rich and untapped corner of the weird, old America with "Boat's Up the River." With Greaseland Studios' mastermind Kid Andersen sitting in on B-3, the band offers some early 1960s juke box funk with "Sookie Sookie." On the album's most surprising track, Andersen returns to the organ for an irresistible take on The Meters' "Funky Miracle." Each piece suggests new directions this band can roam, right up to the closing, saxophone-powered "PM Blues."
