The up-and-coming country artist performs at 7 p.m. at House of Blues. Singles such as the twangy "My Truck, Some Weed, and a Guitar" and the ballad "Everything She Does" suggest Blankenship's straightforward approach. At only 20, Blankenship does write with a great deal of introspection, but he sings with confidence and comes off as authentic on account of the way he embraces old school country ("Everything She Does" benefits from generous banjo).
