Since 1979, it only took Mendoza, Argentina’s Enanitos Verdes (“Little Green Dwarves”) two songs to become one of the most popular rock en español bands ever. Pop hymns “La Muralla Verde” (“The Green Wall”) and “Lamento Boliviano” (“Bolivian Lament”) will still be playing on Latin pop-rock radio and parties after the end of the world, even when only roaches survive. Hardliners wouldn’t find it difficult to dismiss Enanitos as a soft, catchy pop-rock machine. But they’re more than that: If you mix an eternally youthful singer (bassist Marciano Cantero) and the devastating right hand of guitarist Felipe Staiti, coupled with their ability to craft beautifully smart melodies and hooks that grab you by the balls, well … you could do a lot worse than that. Their most recent album, 2013’s Tic Tac, is a fine effort but an excuse to go where the meat is: Enanitos on tour. This is a rare San Antonio appearance, and they’re bringing their usual trio format with the great Jota Morelli (drummer for Fito Páez, Luis Alberto Spinetta, Al Jarreau). A sentimental affair not to be missed. $44-$55, 8pm Fri, Mar. 24, Aztec Theatre, 104 N. St. Mary’s St., (210) 812-4355, theaztectheatre.com.
