Unh! Hurts So Good! Say you were a part of the new roots music movement known as No Depression, when you startled fans by adding a distorted electric buzz to vintage instruments and countrified songs of the open road. Or, say you were a stocky leather-jacketed singer from Indiana who left frat party gigs behind for New York with a cover of Paul Revere & the Raiders' "Kicks" in your repertoire. Say you later returned to the heartland, physically and metaphorically, and parlayed songs about little pink houses and football players who groped their girlfriends in the back seat into a career. Say you married a model, settled down on a farm, had kids, suffered a heart attack, then gingerly made your way back to performing. Now say that each of you took your version of Americana -- lap steel guitars, harmonicas, sepia-toned videos of married couples -- on a cross-country tour together. You would be Son Volt, opening for John Mellencamp. The show begins at 8 p.m. at Shoreline Amphitheater, 1 Amphitheater Pkwy. (at Rengstorff), Mountain View. Admission is $22.50-45; call (650) 962-1000.
