Austin’s Jackson Taylor doesn’t leave much doubt about whether his country-music allegiances lie in Texas or Tennessee: This ain’t no Nashville scene / We ain’t no spiky-haired, half-assed pop-star wannabes, he sings on “Country Song,” throwing in profane jabs at the Grand Ole Opry and Trace Adkins’ “Honky Tonk Badonkadonk” for good measure. Not everything on Aces ’n Eights is quite that pointed, but let’s just say Jackson won’t be needing assertiveness training anytime soon. It’s mostly that brashness that separates this muscle-bound country-rock from the rest of the Red Dirt pack, although “Love Don’t Come Around Here” lets a more vulnerable side peek through.
