To mark the 70th anniversary of John Cage’s masterpiece 4’33’’ Eugene McKeown will hold a short presentation on Quiet Spaces and how to Soundwalk. 4’33’’ is often perceived as four minutes and thirty three seconds of silence but is in fact the sounds of the environment listeners hear while it is performed. The event will repeat every half hour from 6pm to 9pm at the river walk off Bridge Street and will include a performance of 4’33’’ by all participating.
