Mr Underwood is an instrument creator and hacking impresario who loves little more than tinkering with instruments and technology to create new sounds and interfaces, as exemplified in his recent Sonic Graffiti project.
Sonic Graffiti saw Mr Underwood’s previous experiments with leaving sonic electronic devices in public places extended to building new sound-making technologies left in public spaces. The idea is that people stumble across the devices, which are embedded in specific areas, the first of which was Digbeth in Birmingham.
A series of small audio devices were concealed in the area, with a four-composition Crash EP contained within each one. Each piece was based on a field recording taken close to the site in which it was found, which were activated by touch or by plugging headphones directly into the surface where a device was hidden.
For the talk on Sunday, Mr Underwood will be discussing the project and will also allow breakfasters to have a sonic tinker and try making some sounds of their own.
Ideas for Breakfast: Sonic Graffiti & Active Listening takes place on 19 August at W London, 10 Wardour Street W1D. You can buy tickets here
