Nathan Schneidewent, Titan Moon co-songwriter and guitarist, has just driven back from a Saturday night gig in Shreveport, and, boy, is his voice tired. It’s a grateful weariness, at least for the moment, born of the knowledge that the ethereal, imagistic pop rock his quintet purveys is drawing new fans with every show. A few hours before the show, at a club called Flanagan’s, Schneidewent said that he and his bandmates were all on their laptops, “hitting MySpace hard,” trying to drum up Bayou State interest in their show.
