"On 21 Nov. 2004 Leif Brush participated in a Fast Forward performance piece titled Feeding Frenzy at the University of Minnesota, where he is a Professor Emeritus. He collects and generates sounds from and related to the Earth with complex arrays of sophisticated sensors. As part of the live-mixed music for this performance he combined (among other things) sounds from his Terrain Instruments with sounds that emanate from the [ Kosmophone ]. Both musically and conceptually this adds a whole new dimension of anchoring for these sounds. The constant chattering of the Earth is combined with the constant chattering of the stars as if they are singing to each other.
More about the [ Kosmophone ].
Please also listen to Leif Brush's recordings at the [ Tiln restoration pages ].
I have tried to get a grip on the world of Leif Brush, but it is rather complicated. [ Below ] I have included an e-mail conversation which may shed some light." (From the EarLabs' release page)
