Phonopaper used as part of music festival in very cool ways!

In the video they are using it combination with music and it also shows the possibilities as a musician to share ideas and to get a score of your music directly as you can record sound and get a print of the music that can be read later. This is a possibility that have not crossed my mind until this video.
Well read somewhere but can not find it now that Phonopaper is also somehow with prints around the town where the festival is where it is possible to listen to the music of the different artists (if I remember correctly). 
Someday feel that I have to start a Nightradio fanclub!!!
