"Spacedrum" is the name of the song in the video. The instrument is called a "hang" which PANArt will like to remind everyone "is not a drum". This distinction is because if you play the hang like a drum you can damage the instrument by applying too much force.
(The spelling of "Hang" is a little weird. In short, in English, when we make the 'n' sound, our tongue is in the front of our mouth. But in the word "Hang" the tongue is supposed to be a further back like it would be for a 'g' and so the word is spelled with an 'ng'. It may be easiest to think of "HAN" when you try to pronounce the name.)
I haven't played one. But a few things are worth mentioning. PANArt has moved on from making the hang, you may be interested in looking at the other instruments that they are making now and are purchasable through them:

I enjoy making traditional music, but I think they are trying to explore sound in a way different than what I tend to do. I mention this because it might be that their hang is their only instrument that you like.
