"Storytelling is arguably humanity's oldest art form," says Laura Packer, a professional storyteller and writer. "We've been telling each other stories to understand the world and our place in it for as long as we've had language." Her new monthly event, Speak Up Storytelling and Spoken Word, promises six-minute stories (fiction and nonfiction) loosely organized around a theme — this month's is "Firsts" — and related by Packer and storyteller Joyce Slater, as well as audience volunteers. "The stories don't have to be real-life experiences," Packer says. "The more creative the better." Try it at 7 p.m. at Prospero's Uptown (3600 Broadway, #107).
