Saturday, July 30; The District (21 and older): It's unclear what sparked Ian Moore's transformation from a hack version of Stevie Ray Vaughn to an inimitable singer/songwriter with a folky, psychedelic sound. Whatever the impetus for the change, Moore's new and more mature music is a fusion of folk guitar with a country twang that's intensely inviting. His songs have an unmistakable thickness to them that stems from Moore's rich, despondent vocals and reverberating guitar. It's not music that entices you to get out and run a few laps around the park, but it doesn't make you want to lie in bed and mope either. Previous albums have seen Moore journey from funky, FX pedal-injected rock to flamenco guitar rhythms and gospelized singing. With his latest album, Luminaria, however, Moore seems to have found the right mix of spontaneity and continuity. Many have compared Moore's music to bands like Wilco. I, personally, prefer Moore's gentlemanly crooning to Jeff Tweedy's more boyish approach, but both evoke a similar tempo and tone in their songs. Former Mason Jennings' bassist Robert Skoro will open for Moore at The District on Saturday. The free show starts at 8 p.m.
