Tom Johnson - Failing

Here's another piece I recently became aware of in my Music Since WWII class and it's a lot of fun. It's called Failing by Tom Johnson composed for Double Bass. The bass player is supposed to read a written out piece of text while playing little musical figures which get increasingly harder. Unfortunately I couldn't find an example of the score online, but here is a performance (the volume is quite soft, so you'll need to turn it up).
