David Kuckhermann is one of my favorite percussionists.
The “hang” (pronounced “hung”) is a (relatively) new musical instrument that sounds like a hybrid steel drum and gamelan (a Thai xylophone). It is played with the hands or mallets (or whatever) on the lap or a stand and is tuned to make a variety of sounds depending on where it is hit. Hang means “hand” in the Bernese language.
It is made by a swiss company Panart but their web site is now down and they are only making a limited number of instruments duing part of the year. This is an exciting instrument so there should be a used market for it.
