This is the sound of slork, the Stanford Laptop Orchestra.
All instrumentalists are equipped with a black MacBook and a hemispherical speaker pod made out of Ikea tableware.
Recently highlighted at apple.com, slork makes use of custom software written by Ge Wang:
“I wanted to focus on the intersection of music and computer science. So I authored a language with my advisor, Perry Cook, and researchers at Princeton and beyond. We called it ChucK. It’s a programming language completely tailored for sound. It let us quickly synthesize sound and use various controllers in our performances.”
