Folks, come with me. We’re hanging out under some train tracks late at night in Philadelphia doing street art. As the promised companion piece to our wonderful Modern Toichographology episode on murals and street art, this Field Trip takes us to where the action happens, chatting with several muralists as they work on their 17-foot paintings lining Front Street. You’ll meet UNAPXLXGETIQ, El Toro, and Iris Barbee Pendergrass a.k.a. These Pink Lips, Donna Grace Kroh, and Mr. Scoot and learn about their favorite inspirations, methods to making their designs huge, how many Sharpies it takes to outline a building-sized painting, sticker vs. marker vs. paint, graphic and text mural designs, freehand, and most of all, how not to get caught doing illegal art. Onward.
