Our concept is building on previous work in the Oslo Laptop Orchestra:

  • we think of our mobile phones as any other type of instrument, and performs with them as if we had been playing clarinets, trumpets, etc.
  • we embrace the new possibilities that digital instruments allow for, and the social aspects of playing together
  • we only rely on sound coming from the instrument, we never use an external PA system

These rules can be seen as limitations, but they are also liberating and gives the ensemble a clear aesthetic, visual and musical appearance.
