Do you like metal? Do you like mariachi music? Then get ready to feel confused and excited because Metalachi (“the world’s first and only heavy metal mariachi band”) is coming back to San Antonio. The band actually breezes in and out of classic rock and metal with their mariachi interpretations of AC/DC, Guns N’ Roses, and Black Sabbath songs, but it’s their rendition of Slayer’s “Raining Blood” that really hits home in a weird and unexpected way. The members of Metalachi claim they were conceived simultaneously while their mother Consuela Espinosa was high on horse tranquilizers with a jai alai team in a Super Ocho motel in Veracruz. Dressed in lit-up sombreros and costumes supposedly made by child factory workers paid in Chiclets and tacos, Metalachi is fun, ridiculous and oddly impressive.
