Speaking of the Rocky Mountain Rollergirls… they’re holding a fundraiser to help build up the fledgling quad-skate roller derby league. Join the girls (skates optional, attitude required) Saturday night at the Lion’s Lair. Your $5 will be well spent to help keep this punk rock & rolling sport going here in Denver. Four bands — Get Your Going, Paul Lipman, Pandas and Wolves, and Bad Luck City — will likely make your ears bleed at the Lair, a notoriously loud (and tiny) venue.
