The instrument builds from the past few years shown below have been driven by necessity and utility, using freely available materials and, well, adequate tools. The priority with these is function over refinement in the hopes of demonstrating that these are achievable. Maybe some day there will be time, space, and tools to make pretty stuff.
The images below are static, but the creation processes as well as performances can also be experienced on the more dynamic #MUS311 instagram site.
