It’s weird how sometimes you think something is going to totally suck, but then it’s awesome. Like maple bars with bacon on them? I haven’t eaten one, but that seems to be a thing. Pizza and beer. Marijuana and Led Zeppelin. But classic rock songs and mariachi music? That sounds f---ing awful, right? But remember, awful things can be really funny too, and that’s what Metalachi is, mostly. The band mashes mariachi and metal together to perform covers of irrefutably perfect songs like Iron Maiden’s “Run to the Hills,” Guns N’ Roses’ “Sweet Child O’ Mine” and, perhaps the most holy of classic metal songs, Dio’s “Rainbow in the Dark.” You’ve got to hand it to them: it might be kind of irritating to listen to for very long, but it’s pretty hilarious.
