I dug up this old goodie last night.  It was done by Sonom, an experimental group out of Barcelona: “Sonom’s objective was born from the research and exploration of light and sound as universal communication media and as base for integration of other paradigms. The band’s works study in depth relations between waves and human perception. The group developes sound and video projects, multimedia installations and audiovisual concerts. Sonom’s creative position includes hybrid practices, recycled materials and technologies, self-made instruments and digital and analogical devices.” Check out more of their work on Vimeo.
