Ridiculous album covers! Even more ridiculous lyrics! Brothers Ron and Russell Mael began their glam-camp new-wave odyssey more than four decades (!) ago, forming Sparks—one of the consistently catchiest wackadoo avant-pop duos ever. Sometimes the best thing about Sparks is Russell’s wild stage antics and gaudy outfits, not to mention his incredible space-falsetto. Other times, the best thing about Sparks is Ron’s deadpan grimace/smirk at the keyboards, or that mustache. If you’ve been looking for a reason to bust out a silk cape and your freakiest hairdo, tonight’s the night. (Neptune, 1303 NE 45th St, stgpresents.org, 8 pm, $31.50 adv/$35 DOS, all ages)
