Back in 2005 I was in Japan same time as Mr. Natural had his tour there. Our paths crossed for couple of days and played couple same nights, although tours were not consciously organized together.
All he had, was wooden branch, with couple wires attached to it. Contact 2 microphones build in, and two delay pedals. He would make the sound by scratching the wood or working with the wires and making loops or delays with the pedals. Really good stuff.
Already back then, he talked about the difference of releasing noise. That back in the 90's, could just put out 7" and people would actually order it after seeing flyer. Later on things became quite different and guy doing small release once in a while, with no website, no proper mailorder, etc... I think he did few things selling them only at gigs?
