Kevin Cervera is the puppet master behind Guanajuato’s Hexagrams, a post-punk/shoegaze foursome that’s heavy with the shimmery guitars and spectral voices. Fittingly, the closing track from their latest EP, Analog, is titled “Ghost,” and the other two tracks from this three-song package are titled just as hauntingly: “Disappear” and “Existence.” Analog is catnip for anyone interested in The xx or general fans of moody/seedy dance tracks. You can download it on a name-your-price basis on the group’s bandcamp.
