 It's an admirable outlook to have in the oft-stuffy world of Nashville formalism, and it has led his band to multiplatinum success.But the group's fourth studio full-length goes miles beyond even their most off-the-beaten-path excursions, and not always for the better...Though Brown's vocals adjust to "Jekyll + Hyde"s multiple personalities, he can't provide enough continuity to keep the album cohesive, and the borderline-goofy gambits are more distracting than interesting.The album certainly proves that ZBB have range.
