Has digital music reached the point of diminishing returns? Has it all been done, and heard, before? At the start of a new millennium, a crew of Princeton engineers and musicians answered this question with a resounding no, building the now-famous Princeton Laptop Orchestra. As a Princeton music grad student in the late 1990s, Dan Trueman worked with his adviser, Perry Cook, on building an unorthodox digital instrument played with all the expression of a fiddle, but sounding more like a robot. And rather than running the sound through a single speaker pointed at the audience, they created a 360-degree ball of speakers, so that the device had the sonic presence of an acoustic instrument. When Trueman returned as a member of the faculty several years later, Trueman and Cook (who had a joint appointment in engineering and music) set their minds to creating an entire ensemble of those unorthodox instruments. And in the process, they created a whole new genre of music and digital creative expression.
