If Muscle Shoals and the U.K. can have their own brand of soul, why can’t the Southwest? That’s why the Villanueva brothers (Abraham, Rene and Jaime) and guitarist cousin Dante Schwebel formed Hacienda. The quartet blends rootsy twang with supple R&B sway and Beach Boys harmonies on their first two Dan Auerbach-produced albums. The Black Keys guitarist takes an even larger role on their latest, Shakedown, contributing to the songwriting (as he did on Jessica Lea Mayfield’s last album) in addition to producing. It results in a grittier blues-funk scaffolding for their retro ’60s pop/rock fascinations. The soul’s still there, as are the harmonies, but they’re downplayed in favor of warm, hook-laden propulsion that’s more contagious than Ebola. Danish opener Teitur Larsen explores a ’70s singer-songwriter mien replete with soft-rock atmosphere and perky mid-tempo tilt. His flitting tenor and fey, literate manner recall Ron Sexsmith and Jens Lekman.
