The mind-blowing a capella quintet Pentatonix ("The Sing Off") arranged this already super-cool Imogen Heap tune from "Ellipse", and my job here was to thicken it up and make a few tweaks that helped it fit a larger vocal jazz ensemble.  There's some added complexity, compared to their version, but the chart retains their futuristic spirit and nuance.
