In a sense this has become an instrument in itself, as demonstrated in these rather poor clips. This method of playing was used most recently on my CD, Catch the Squirrel.
The Drum Tree is definitely a work in progress. This picture was taken 2/28/09 and shows the current configuration. This “instrument” was a product if the rather crammed quarters of my studio space over the years. There’s never been enough space for a drum kit, so I’ve just accumulated a collection of various percussion items. There’s not exactly room for a percussion table, so I’ve devised a way to maximize my space while providing access to a good selection of sounds nonetheless.
