an approach to sound, based on using and altering specific, recorded, concrete audio material. manipulation is limited. in the tradition of the musique conrète the concrete sonic material is the starting point of the compositional activities. the work unfolds from there - not from a master-method or grande idea or score determining the structure of the piece. unfolding, not imposing. most often resulting in ACOUSMATIC compositions. through manipulation of the concrete material different degrees of source regonition are achieved. [durchdringung des materials wie das formen und kneten des tons.]
