Work Details
For the summer months of 2005 and 2006 I took part in a number of interdisciplinary art festivals in Morocco. These recordings, made in Marrakech, are examples of context-responsive electro-acoustic improvisations made by an ensemble of 4 players assembled for the project. A strategy based upon genetic algorithms, that is to say, a collaborative process of selection and modification of sounds was developed, prior to performance, in order to create cohesion and a group identity in, at times, quite difficult circumstances.

Genetic Algorithms: Rules of Evolution

1 each directory represents the gene pool for that 15 min section of performance. contribute as many specimens as you see fit (15 max?) =a lot of genetic material to become familiar with

naming conventions: ritual001-01.wav

means ritual sound file 001 – first generation

after a generation of evolution it would become
ritual001-02.wav

a further evolutionary step would result in
ritual001-03.wav

and so on
ritual001-04.wav
ritual001-05.wav
….

3 it would be interesting for each dna strand (sound file) to go thru a minimum of 4 steps

i.e to pass thru each of the ‘fitness selectors’ following the original entry into the gene pool.

adam
cate
ed
joel
milo

4 process
once you have downloaded the all the material, have a listen and assess the sample’s fitness for selection or rejection.

material selected is to be subjected to one of two processess

genetic splicing – dna from two selected samples is exchanged
mutation – dna is subjected to audio processing, and mutated into the next generation

nb/ neither of these processes should be applied to the entire strand, only sections of the strand may be processed, leaving some of the previous generation’s dna intact.

upload the next generation, with their new tag – e.g ritual001-01.wav, after modification, will be renamed, ritual001-02.wav

kill the parents (we should leave the originals online, but they are now unfit, and should be rejected)

by the end of this first stage of the process we should end up with a number of files:

ritualxxx-05.wav
ritualxxx-05.wav
ritualxxx-05.wav
ritualxxx-05.wav
ritualxxx-05.wav
ritualxxx-05.wav
ritualxxx-05.wav

these will serve as our genetic base for the improvisations in marrakesh
