Improv in Toronto's latest action subway dance party took place on February 21. 450 people participated in the dance. The concept is get on the subway, listen to your music on your mp3 player and start to dance until a) people start to join you, b) people get scared and get off the subway and consequently the authorities tell you to stop the dancing. It's kind of like that silent rave party, but the spontaneity of it makes it even funnier.
