As a bonus I'm including an example taken from Wolf Kerschek's score Brazilian Walz. As far as I know this has not been commercially recorded, but was played by the NDR Hamburg Radio Band.
The example, at first glance, looks like a very simple passage for marimba. It is, in fact, highly complex. Try and play it on your keyboard. The sound clip was made by playing the example in Encore 4.5.
