Now That's Class continues a fine tradition of kicking off the work week with a good dose of heavy metal music. At tonight's Metal Mondays celebration that's dubbed Thrash Your Tits Off, DJ Shaun will spin all the best speed metal and thrash metal and whatever-other-kinds-of-metal-you-can-think-of on vinyl from 9 p.m. to 1 a.m. The event coincides with WCSB's all-day metal blowout. Admission is free and the club offers $2 PBR and Olde English tallboys too. (Niesel)
