As part of this year’s Humana Festival, Actors Theatre has invited the leaders of a number of local festivals to take part in a panel discussion Saturday on Louisville’s festival culture. Representatives from the IdeaFestival, Festival of Faiths, Derby Festival and the St.James Court Art Show will take part in the discussion titled, “Louisville: City of Festivals – The Ecology of a Great Gathering Place.”“As we celebrate our 35th anniversary of the Humana Festival and with such a plethora of vibrant festivals happening in our city, I think this is a great opportunity for all the different leaders of those festivals to get together and really delve into some of the questions surrounding how Louisville has evolved to be such a great festival city," says Actors Theatre spokesperson Kirsty Gaukel.Last year, Louisville was awarded the World Festival and Event City award from the International Festival and Events Association.The discussion begins at 11:00 a.m. at Actors Theatre. The event is free, but tickets are required for admission.
