The piece isn't a joke or anything like that, and there really isn't anything to "get", any more than there is something to "get" about any other piece of music.

It is like the "Running Fence" and a lot of other related art projects--if you to ignore the apparent absurdity of the components(and consider that all art is constructed from absurd components), and are open to what happens, you will experience something worthwhile--

There is another side to this as well, which is that if you can't open yourself up to what is happening in this piece --are really open to what happening in Beethoven or Charlie Parker or in that old tape of "All Around My Hat" that you make everyone listen to on every possible occasion?
