Just came across this interview with Hauschka – a German artist which I love. He plays “prepared” piano — a piano that has been modified by hardware additions. For a typical piece, he makes more than 20 adjustments to the innards of a grand piano using duct tape, felt, cellophane, bottle caps, wedges, aluminum foil, sheets of paper. I was reminded of our Metal Music and The Sound of Marbles.
PS: Michael S-W, hope you read this! I was in Berlin for a week and got to see some great shows!
