Lecturing on topics one knows nothing about may be a liability for professionals, but for participants in Sheila Heti’s Trampoline Hall lecture series, it’s a requirement. Since late 2001, the monthly Toronto-based talks have been a fixture of the city’s arts scene, inviting speakers to wax poetic on topics ranging from “The Lazy Sociopath” to “Secret Eating” and “Teenage Circumcision.” In honor of the Heti and Misha Glouberman’s new book, The Chairs Are Where the People Go, they’ve taken the series on the road, and will appear tonight for a book-promo-cum-Trampoline-Hall event at the powerHouse Arena in Brooklyn with writers Sara Marcus and Adam Sternbergh.
