The night after I first heard Wars (Polyvinyl), the latest from Bay Area combo XBXRX, I had a dream in which one of the band’s members whispered to me that their name means “sebics sericks.” I was struck dumb by the righteous meaning of this: it made absolute sense then, and of course absolutely none afterward. Which is a reasonable metaphor for Wars itself, a topsy-turvy car crash of an album (12 songs in 28 minutes) full of swerves that seem only moments later to be in clear defiance of noise-rock physics. Formed by a group of postadolescent Alabaman miscreants, the band later moved to San Francisco, where they picked up former Chicagoan Weasel Walter, whose manic Morse-code drumming now powers their tweaky, impossibly dense artcore. While their shows are notoriously riotous (both onstage and off), the vibe I get is one of an almost wholesome rambunctiousness–like they’ve somehow managed to retain the chemical makeup of 14-year-olds, full of hormones and high fructose corn syrup.
