But Folsom isn't a chronic navel-gazer. Like Susan Tedeschi, an artist with whom she shares a blues bent and a vocal prowess, her bawdier moments are her most satisfying. "Natural Disaster," and "Lift Me Higher" roll with pure New Orleans-style R&B, flushed out by wailing saxes, Wurlitzer and B-3 organs and the occasional searing guitar solo. It's a busy, gospel-flecked stew that could have easily leapt right over the top. But Folsom doesn't confuse soul with self-indulgence: Her songs are like little earthquakes: rattling and unexpected, but over before you've really figured out what's hit you.
