Watch: A Trombone, A Looping Pedal And A Colorful Collage Of Sound

Sipher plays a few bars on his instrument, lets the loop pedal record it and play it back, and then adds more intricate layers over the original pattern. The music includes unusual beatboxing and a wall of gorgeous harmonies in the piece's surprisingly tender later passages. 

I could go on, but you have to see and hear it to really experience it. Watch Sipher's original composition "Changes" in the video link above.
