Halloween falls on a Monday this year, meaning the preceding weekend is going to be a circus of slutty zombies and pirates drunkenly scarfing vendor hot-dogs on the street. Yet some might prefer to observe the holiday in a more reverent manner, with a celebration of the metal rock sounds that drove many an ‘80s mom to wonder if Junior was a satanist. For them, there’s Metalween, a marathon bill of no less than nine Black Sabbath, Judas Priest, Iron Maiden, Pantera, and Danzig cover bands who plan to slay all who attend with the merciless hand of heavy metal. We highly encourage the throwing of rubber bats on stage. With Hand of Doom, At The Spine, Danzig With Wolves, Call The Priest, Thunderpouch, Vultures 2012, Post Adolescence, Darfunkel, Smile For Diamonds. GWENDOLYN ELLIOTT
