Craig Colorusso’s “sun boxes” is an environmental instrument consisting of twenty solar-powered speakers that contain PC boards loaded with pre-programmed and pre-looped guitar notes. The rising and setting of the sun influences the music, as does the listener’s position amongst the boxes. Or, as Important Records puts it:
Sun Boxes are an environment to enter and exit. It’s comprised of twenty speakers operating independently each powered by solar panels. There is a different guitar sample in each box all playing together making the composition. The guitar samples are all of different lengths so the whole piece keeps evolving.
Participants are encouraged to walk amongst the speakers. It sounds different inside of the array. There is a different sense of space inside. Certain speakers will be closer and louder therefore the piece will sound different to different people in different positions throughout the array. Creating a unique experience for everyone.
There are no batteries involved. The Sun Boxes are reliant on the sun. When the sun sets the music stops. The piece changes as the length of the day changes. Making the participants aware of the cycle of the day.
