When I lived in Chicago, consistently my companions and I advanced toward ImprovOlympic, at the intersection of Clark and Addison, to watch groups perform long-shape improv (known as “The Harold”). The house group was called “The Family”: six madly skilled men, every one of whom examined with master Del Close, and every one of whom who have gone ahead to colossal achievement: Adam McKay, Neil Flynn, Matt Besser, Ali Farahnakian, Ian Roberts and Miles Stroth. Individuals like Tina Fey and Amy Poehler regularly “sat in,” performing with the gathering.
Those shows are still unbelievable to anybody sufficiently fortunate to have been there. In great improv like that, individuals speak with lightning-speed through ESP and intuition.
