Along Those Lines...

This ties in nicely with the previous post. Here is a performer [Imogen Heap] who is singing a capella and harmonizing with herself using a looper. This was performed live at a radio station. Part of this song appears in the movie "The Holiday." Imogen Heap has also been a major inspiration to classical living composer, Eric Whitacre.

This video shows a group imitating instruments using the human voice and body [i.e. clapping hands] and a pedal looper as well as special microphones. It's quite interesting, and I enjoy the reference to their a capella barbershop roots.
