The popular local dance group, Philly Thriller (Facebook page), which holds Michael Jackson inspired flash-mob performances on the streets of West Philly every Halloween, will be entertaining the crowds this year as well. We got in touch with the group director Rashida Holmes to see where folks can catch them this Saturday. According to Holmes, they’ll be at Clark Park (43rd and Baltimore) tomorrow from 5:30-6:45 p.m., so don’t miss their performances. For more Halloween events, go here.
