The organizers of tonight’s talk have branded it as a “raw exchange”—part of a series of uncensored literary gatherings around the city—and so they’ve invited three biting B.C. writers to get down to brass tacks for a group of strangers in the basement of the Vancouver Public Library. By some freak of programming, a punk-metal band is slaying the kids in the room down the hall tonight, which means every time a bookish-looking latecomer wades into our midst, a foul-sounding wave of hellish power chords does, too.
