Now in its fourth season, the local branch of The Moth Storyslam — which takes place on the last Tuesday of every month — gives everyone the chance to get on stage and share a five-minute story that pertains to that month’s topic. This month, the topic is Heat, a particularly open-ended one even by The Moth standards, which should produce some stories from across the spectrum. To participate, just show up a little early, sign up and, from there, it’s luck of the draw, resulting in 10 storytellers.
