Few are willing to hazard a guess on how to pronounce UUVVWWZ‘s formidable moniker. For the record, say: double U, double V, double W, Z, which you may want to practice in front of a mirror a few times before heading to the Jackpot Saturday night. With nebulous song structures, chanted vocals and that secret-handshake name, the Nebraska group has draped itself in willful obscurity. The band’s self-titled debut, released last year on Saddle Creek, brims with art-school punk. If there’s such a thing as vibrant minimalism, UUVVWWZ are experts at creating it, and their chaotic live show is proof.
