Extension I is the first in a series of works aiming to extend the sound quality of certain live instruments. In this piece it is the cello. Its sound is manipulated in different ways - from a low degree of manipulation, e.g. transposition, to an extremely high degree,e.g. a combination of layerings of loops and permutations with help from a Buchla synthesizer. The manipulated sounds are then juxtaposed with some pieces of the original sound material, in order to give depth to our perception of the instrument. The piece was made at the Electronic Music Studio in Stockholm.
