CONCERTOS by No Collective
A musical notation can either describe an event that has already happened or prescribe an event to be performed by the reader. No Collective's (You Nakai. et al.) Concertos, the second book in the Emergency Playscript Series, uses both description and prescription to notate a musical performance. The original Concertos premiered in 2008 in Tokyo, performed by four musicians, a dog, a bird, and several guests. The playscript evokes the original piece while embedding the experience of reading the playscript into any subsequent performances of the piece.
