Grandma didn’t knit all that ugly for no reason! You can finally get some mileage out of the awful cardigan she sent last winter at GBDC, which will get in the holiday spirit this Saturday to hideous effect. And if she sent a matching beanie and mittens, well, wear those, too. DJs on duty include Mark Stylz and Presto One. December 21, doors at 1 p.m., $20 men, $10 women, local men free before 2 p.m., local women free.
