It’s not often that my unused music degree intersects with the topic of this blog, but I got an email from Craig Colorusso describing a neat, solar powered public art project that he’s touring the US with called Sun Boxes. From the description on his website:

Sun Boxes are an environment to enter and exit at will. It’s comprised of twenty speakers operating independently, each powered by the sun via solar panels. There is a different loop set to play a guitar note in each box continuously. These guitar notes collectively make a Bb chord. Because the loops are different in length, once the piece begins they continually overlap and the piece slowly evolves over time.

You can find out more about the project at www.sun-boxes.com. Make sure to listen to the recording of the boxes–I could listen for hours–the sound is at once hypnotic and deeply relaxing.
