After becoming involved in protests against a Willamette River hydroelectric power project, Williams began to think of how the river itself should have a voice in its fate, and eventually collected over 400 songs about rivers, which he crafted into his program Of Time and Rivers Flowing.

Williams has performed the program for benefits, conferences, and in concert.
