Heartless Bastards’ third album brought a major lineup change for the blues-rock unit, leaving lead singer/guitarist Erika Wennerstrom as the last woman standing. The group shifted to a more refined sound than on their rugged earlier albums; here, acoustic songs like “Could Be So Happy” find Wennerstrom tackling a folky stride, while stormy tracks like “Early in the Morning” show the group’s penchant for balancing upbeat grooves with gnarled riffs.
