(Barboza) Damn, no matter how many times I try, I can't correctly spell or pronounce Ahleuchatistas's name on first attempt. However, I can immediately lock into the Asheville, North Carolina, duo's fiercely inventive and tentacular prog rock. (Some will call it math rock, but that is just prog made by dudes with short hair in the time after punk burned itself out.) Anyway, forget terminology: Ahleuchatistas (guitarist Shane Perlowin and drummer Ryan Oslance) play a bracing strain of abstract-expressionist rock with mercurial dexterity, coruscating precision. Their Heads Full of Poison album bears traces of '80s King Crimson, Steve Reich–ian minimalism, and African trance music whose exact origin's hard to pinpoint. It's one of the most fascinating and wild musical joyrides of recent years.
