I got this link in an email this morning and just had a listen. Its totally awesome to say the very least. I know there are some whistle players who also play Didj. The track is called “Whales”.
I have heard many, many Didj and Whistle tracks and they go very well together. The person that you have heard or CD track must need to do some more work as these 2 instruments do not cause war and or strife.
I didn’t listen to the track because I can’t be bothered to sign up for mp3.com. But if you are into whale sounds and things, you should check out a recording from the eighties by Albert von Mangelsdorff, on of the greatest jazz trombonists ever. He was known for perfecting the knack of signing into the horn while playing, and so creating harmonies. I forget the name of this recording, but it’s whale sounds and Mangelsdorff and his horn and his harmonies. Quite wonderful, if not everyone’s kettle of fish, pardon, mamal.
