Mutations, commissioned by cellist Jan Müller-Szeraws, blurs boundaries between acoustic and electric sounds with the aid of an interactive Max patch that alters the sound of the cello in real-time. Complementing these alterations, which range from bright echoes and spiraling Doppler effects to microtonal distortions, ghostly harmonizations, and whispered glissandi, are prerecorded sounds modeled largely after spectral permutations of cello timbres. These prerecorded sounds mix with the live cello during a performance to create timbres that are neither entirely acoustic nor entirely electronic but rather hybrids that paint new sonic possibilities on a canvas of soaring virtuosity cast in the coloratura of the instrument.
It's an interesting work although I'm trying to decide if "a canvas of soaring viruosity" counts as hyperbole. Jan Müller-Szeraws is the cellist.
