From the Symphony of Science site:

Hey – I’m John Boswell, the musician and producer behind the Symphony of Science. The goal of the project is to bring scientific knowledge and philosophy to the masses, in a novel way, through the medium of music. Science and music are two passions of mine that I aim to combine in a way that is intended to bring a meaningful message to listeners, while simultaneously providing an enjoyable musical experience.
