Chicago writer and performer Ian Belknap has sent out the call, and a group of authors will take up the challenge. Write Club, a three-round literary equivalent of a bare-knuckle fight out behind the dumpster, happens tomorrow night at the Hideout. Each pair of participants is given a theme to write on, and in just 7 minutes they have to write the stuffing out of each other. Full details of the event in Slowdown.
