Last year I saw Pierre Bastien play live. Interesting how machines can act as a musical instrument and provide musical layers to improvise on. But it also appeared hard to keep it interesting as there is not much variation in the turning of a wheel.
Roman Gerold was kind enough to share his latest experiment with me: Lego Tinguely 2: a mechanical rhythm machine made of Lego. A great idea to use such simple building blocks to generate noise and rhythms. Its sounds could play a role in a musical setting as well, if used in moderation.
