San Francisco is full of hidden surprises. The morning found me in San Francisco, having made my way to the Marina District to look a a project I’ll be photographing for a client. Having left the project I was in no hurry to make my way home with such a clear crisp day and the waterfront of the Marina beckoning me. I was on foot, having arrived by way of public transportation using BART and bus. Looking at a map and I noticed something at the end of the jetty labeled “Wave Organ. Unique acoustic sculpture on the bay.” I was intrigued so I made my way to the end of Marina Green Drive and on out to the end of the Jetty. The Wave Organ is a wave-activated acoustic sculpture. The concept was developed by Peter Richards and was installed in collaboration with sculptor and master stone mason George Gonzales. Installed in 1986. To really appreciate this you need to sit on a bench and just let the sounds wash over you; a very subtle and gentle experience. In addition to the wave organ, the location offers a spectacular view of San Francisco Bay with the Golden Gate Bridge and Alcatraz in the distance.
