Austin bassist Andrew Duplantis (Son Volt and Jon Dee Graham) made an inauspicious St. Louis debut as a solo singer-songwriter at the well-intentioned but disappointing 2005 Mound City Music Festival. His new album with scruffy young band the Unfaithfuls, Colorblind, suggests the heyday of vaguely twangy Austin rockers the True Believers and Loose Diamonds, albeit augmented with synth whine and sub-Farrarian abstruseness. "Talking backwards, is it possible?" Duplantis, his voice buried in guitar noise, seems to sing. "All directions outside in mutilating any silence." Translation: He's still on the verge of a confident songwriting voice. But when he plugs into elemental power pop on "Next Question" and "Backpedaling," Duplantis sounds like he's moving forward, and ready to arrive.
