With its unrushed mood and old-fashioned textures, Los Del Arroyo’s lilting 2018 album brings a welcome change of pace to contemporary regional Mexican music. Seeking to recapture and celebrate the essence of the country’s folklore, the band anchors its sound on spidery acoustic guitar lines and soulful vocal harmonies. The result is a collection of songs that switch between lively corrido grooves and sweet romantic ballads, betting on elegance and understatement throughout. The title track, a collaboration with La Última Sentencia, adds a few touches of banda sinaloense bravado to the mix, while closer “La Estrategia del Maestro” shines on the strength of thoughtful lyrics and a gorgeous melody. It all brims with the type of idealism that’s central to Mexican folk music.
