Zombies are not only dancing in the streets, but they're doing it like pros, thanks to DanzArtz' series of Thriller-specific Guerilla Thrilla classes that teach Michael Jackson's classic video dance sequence step by step to anyone willing to offer up their time and the class fee. On Halloween night, close to 250 students donned zombie togs and makeup and danced the routine in Skyline Park; later, some of them repeated the feat in the Congress Park neighborhood. Fields and crew say they're on board for the event again this year, but it'll go down with a twist: an Addams Family theme. Get ready for a Fester occasion.
