It is indeed a rarity when a pop group as significant as the Faxed Head makes a local appearance. The band formed a decade ago by several glue-sniffing high-school students from this godforsaken community in western Fresno County who’d found a box of “death metal” cassettes in a box strewn along I-5. Intrigued by the music’s darker passages, they first attempted suicide via large-caliber firearms; when that resulted in severe mental impairment rather than membership in the Judas Priest fan club for the permanently horizontal, they did the next most logical thing and formed a band. Monday’s gig at Old Ironsides, 1901 S St., marks one of the only two dates the Faxed Head will play in the U.S., in support of its new CD, Chiropractic (available on the Web of Mimicry label through Revolver Distribution). The must-see show, which also features the substantial talents of the Karaoke King and Rick Rizzo, starts around 9 p.m. Call 442-3504 for cover.
