As far as commercially viable musical combinations go, tribal rhythms paired with chanted vocals is a proven formula for success. Right now, the members of Enigma are probably entertaining a couple of purebred wolfhounds in a replica Neuschwanstein castle that they built with the royalties from MCMXC a.D. Though Los Angeles’ Health isn’t likely to ride its zombie chants into such monetary reward, the band’s edgier spin on the drums-and-voice sound is at least as catchy as “Sadeness (Part I)” ever was. Amid tinnitus-inducing synthesizer squeals, Health pounds cyclical rhythms and cold, unintelligible verse through a rack of effect pedals. Imagine a group of Gregorian monks imprisoned within a game of Q-Bert, and you’re not terribly far off. Health is a little noisy for FM-lite, but it can definitely still help one zone out. Health performs with the Apes and True Womanhood at 9:30 p.m. at the Velvet Lounge, 915 U St. NW. $10. (202) 462-3213. —Aaron Leitko
