They perform their music live on iPhones. MoPhO's music director, Ge Wang, earned his PhD in computer science from Princeton. Teaching as an assistant professor of music at Stanford's Center for Computer Research in Music and Acoustics (CCRMA), Professor Wang is also founder of the Stanford Laptop Orchestra and a hi-tech entrepreneur. His start up company, Sonic Mule (or SMULE), was founded in July of last year to explore interactive sonic media.
MoPhO is not your fathers' ring-tones.
