BEST FLANNEL REVIVAL

In this age of continual retro, it comes as a surprise that listening to mainstream '90s alternative rock can give you, under the right inebriated circumstances, the kind of pleasure not experienced since heroin went out of vogue. Debaser at the Knockout has become one of the best monthly parties in San Francisco, largely because it gives '80s babies, who were stuck playing Oregon Trail in computer class while Courtney Love and Kat Bjelland were rocking it out in Portland, the chance to live out their Nirvana-era dreams. Debaser promoter Jamie Jams is the only DJ in San Francisco who will spin the Cranberries after a Pavement song, and his inspired mixology is empirically proven to induce moshing en masse until last call, an enticingly dangerous sport now that lead-footed Doc Martens are back in style. Sporting flannel gets you comped, so for those still hung up over Jordan Catalano and the way he leans, Debaser is rife with contemporary, albeit less angsty, equivalents.

First Saturdays, 9 p.m., Knockout, 3223 Mission, SF. (415) 550-6994, www.myspace.com/debaser90s
