Cool Music

This is very cool:

Here is an article on the composer and instruments. I'm a little puzzled about the details because it seems to me that while ice horns are quite feasible, an ice harp or drum would be problematic. Ice doesn't seem to have any potential as a vibrating body--as opposed to wood. So, unless you are amplifying electrically, I can't see an ice harp as making any amount of sound at all. And the ice drums he is playing sound like they are made of wood. Well, they're not, of course, but perhaps there is a drum synth pad on top? Just wondering.

But the music leaves me cold...
