Violinist Jon Rose is a unique musician: he builds and plays weird string instruments. And oh, he plays music on fences.
Yes, fences: this one above is a barbed wire fence, made and played on as part of the New Music Festival in Viitasaari, Finland in 1995:
It was modeled on the border that separates Russia and Finland. Then came the idea to make an experimental radio work... an endless fence that circumnavigates the entire world, incorporating many of the conflict zones that seem unresolvable or remain as scars on the psychology of the people who must live on each side of these artificially created borders.
