Happy ImprovBoston Day!

In recognition of 29 years in operation, in Inman Square and now in Central Square, the City of Cambridge has declared September 9 "ImprovBoston Day." You can read the official declaration here. The proclamation provides an interesting snapshot of IB's history, going back to its founding by former Second City student Ellen Holbrook in 1982 and the fact that it once operated in a club owned by former Celtic Satch Sanders.

IB kicked off its Second Annual Boston Improv Festival last night, which will bring over 100 performers to three stages through Sunday. Acts come from all over the country, and a few, like We're From Here, WDWMKR, and Montreal Improv, from Canada.

Joe Bill also returns Saturday, but not with his usual act, the fantastic duo of Bassprov, which has played the Lowell Comedy Festival in the past. And the North End comes to Central Square when Improv Asylum brings its new mainstage show, Hungry, Hungry Hipsters to ImprovBoston Sunday.
