In the first 7 minutes or so you can hear Medial Ages getting used to the lighting which was not completely dark (affecting the light sensors) and playing the Signum in a performance for the first time. I brought my Signum upon request and she had a few minutes to figure out how it worked before she started. I like this first part the most in a way.. Its more abstract form the rest of the piece. There is less thinking and finessing involved, it is instinctual and reactive to the environment which produced it.
7minutes she gets into it bird like calls
