Frog City was inspired by the sounds of foghorns, which I have often listened to and recorded in San Francisco. Each sound in the piece is either a foghorn, or partials thereof. In a sense, the piece is about the ways in which the foghorns -- initially pillars of solidity -- break up into harmonics, in much the same way as other solid entities start to seem much more malleable when engulfed in fog. I also wanted to create a visual analogy for this process by gradually processing antique footage more and more intensely.

As for the title: a young friend of mine, hearing the word "fog" for the first time, kept asking: Where are the frogs? And I started to imagine the piece also as a chorus of slowed-down, otherworldy frogs.
