As the Airstream trailer on the back cover of his latest disc suggests, folk/pop singer/songwriter Darden Smith likes to keep moving. On Circo, Smith emphasizes melodic structures that are comfortable yet tuney, filled with crisp production values. What lifts these pop songs above the commonplace is their lyrical attention to life’s subtle details and big questions. Alongside guest vocalists like Shawn Colvin, Suzzy Roche, Kim Richey, Jim Lauderdale and one-time partner Boo Hewerdine, Smith rises to the occasion. Creating moving music, emphasizing craft as a guide to the inner spaces.
