That looks really cool and it some super editing. Not too sure about the Tesla coil and globe, though. The way he does it in the vid, he makes it look like he's playing notes on the globe, but that's not the case at all, as you can see his other hand playing the keyboard. That's not to say you couldn't somehow rig a globe to trigger notes.
Also the sound they're using at the end to trigger the water cascade isn't the kick drum..but the effect looks exactly the same.
Sorry..not dissing this at all..it's really cool..but there's a fair bit of "showmanship" gone into this and I think not all of what you see is the result of sound waves on matter, as is implied.
Maybe I'm wrong..IDK.
