This is David.
He is playing a tree branch as a musical instrument. I heard a flute, a tree frog, a synthesizer, a drum and a steel guitar all come from that lovely piece of tree.
It was the most incredible, amazing, spiritual experience. I spoke with him after his performance. He talked about the healing nature of trees, that he'd taken some branches inside his house and hung them to remind himself of how those qualities. One day he bumped into a branch and noticed its tone. So then he tapped on another branch and it had a different tone. The music naturally came from the branches. A creative man, he found a way to wire it up and share that sound with others. I've been ignoring the picture aspect and simply listening to the videos for days.
