Buck Owens’s influence always loomed large in this Austin band’s jangly, Bakersfield-meets-Beatles sound. But with these 12 Owens originals (and one Bakersfield-ified “Johnny Be Goode””), the Derailers appear to be not just covering but actually channeling the king of California country. The arrangements — raw pedal steel, crisp, twangy Telecaster, hard-driving drums — are faithful to the point of reverence, and Brian Hofeldt’s pleasant tenor mimics Owen’s phrasing to an almost startling extent. Therein lies the danger: when the tribute sounds so much like the original, why not just skip the middleman and hit on some straight-up Buck? The answer, in this case, is the energy of unabashed fan-dom. With Under the Influence of Buck, the Derailers bring to life the kind of excitement that makes musicians take up the honky-tonk life in the first place. (It’s certainly not the health plan.) And though the songlist sticks mostly to Buck’s bigger hits, the highlights are actually the lesser-known, not-quite-classics: the fuzz-laden, pyschedelic guitar of “Who’s Gonna Mow Your Grass,” the lovely and uncharacteristically countrypolitan “Big in Vegas.” If the album drives some young listener deeper into the arms of Buck’s backlist, why, in this case, they could do much worse indeed.
