To BT, it’s all ones and zeros. “Music is just applied mathematics,” he says. “And so is visual art — it’s all related. You’re just dealing with color instead of the audible spectrum.” For this musician-composer-sound artist, the universe is, simply put, binary. And his latest project is a pure expression of that philosophy, an artistic fusion of digital music and motion, wrought in surround sound and digital video. “This Binary Universe” isn’t exactly an album and it isn’t exactly a motion picture. It’s a new form of digital art.
