In case you’ve missed this: in 2013, 18 music producers made a long collective composition that lasts a bit more than 43 minutes. They used a method which we call Cadavre exquis de la musique: each of the participants was in charge just for one fragment, and the final result remained obscured during the entire working process. Finally, we revealed it and published on this very website under the name “Foldout”. It is available for free downloading, so you can give it a try at any moment. Right now, for example.
