Awesome post at musicofsound dedicated to the great work of recordist/artist Toshiya Tsunoda:
My field recordings feature the transmission of vibrations, and any location can be interesting. The question is what is happening in actual vibrations in a specific place. I picked several different locations and repeated recordings to see the depth of activity, which has slight differences every time. Any particular place forms a pattern of vibrations that is specific to the place depending on the physical condition of the space. By seeking the point for recording, I search for the nature of the place.
(Tim also leaves some mystery in the post: “And lastly, a slightly secret piece of advice: if you are considering buying a contact mic for recording I would hold off for about a month. Some very interesting developments are afoot…. and that is all I can say!”)
