An only-in-San-Francisco tradition since 1998, Black X Mass is a sometimes shocking, always titillating variety show hosted by Karla LaVey and the First Satanic Church. If you were good all year, kick off a debaucherous slide into 2018 with performances by From Hell, Sexstar, Suicide Queen and many more. You can also expect free party food and fun giveaways — this is church after all.
