Nono-Orchestra (Klaus Wiese) - A-Kaori

The members of Nono-Orchestra use what appear to be enormous sections of sheet metal formed into resonant instruments which make pluritimbral vibrations and layers of very low frequencies noise.
This is very different than other deep noise projects. Often electronic artists create low noise using electronics and feedback but the sound here are formed much in the same principle of acoustic music. Various members of this quartet actually employ bows to create the vibrations of the metal in much the same way that a string musician would play his instrument. The result is an original and  audibly vibrant low noise experience. Very textured, fascinating.
