An era ended two summers ago when Richard Cotovsky pulled down the curtain on his long-running Abbie Hoffman Died for Your Sins Festival. Cotovsky first started the fest in 1989, the year of Abbie Hoffman’s suicide, to commemorate the 20th anniversary of Woodstock, and at that point he was ready to move on. “The Last Abbie Fest” was meant to be just that, a fact reflected in the poster: a skull with a flag bandanna, hippie glasses, and Hoffman’s trademark Jewfro.

This year’s edition, which coincides with the 50th anniversary of the Yippies’ six-day Festival of Life in Chicago, promises to be even bigger, with 101 acts.

Fri 8/17-Sun 8/19: Fri 7 PM-4 AM, Sat 1:15 PM-2 AM, Sun 1-11 PM, Prop Thtr, 3502 N. Elston, yippiefest.com, $25 weekend pass, $15 single-day pass.
