Hang

The Hang (or Hang Drum as it is often referred to) is a tuned 

steel idiophone developed in Switzerland in 2000.

Buying one of these doesn't exactly seem to be the easiest thing 

on earth. They only get produced by ONE company (2 people), 

which are the same guys who created the instrument in the first 

place. Rumors spread you have to pay up to 6000$ on the 

blackmarket (ebay) orrrrr...you order directly and wait for...ahemm...

a long time before you can get one. Contact by letter only. 

More information is available here

Still, the Hang produces some of the most amazing sounds 

I've ever listened to. Watch the video and judge for yourself.
