I've never heard of The Orb. I am a huge Gilmour fan, so I will be checking this out.
I'm interested in the 3D stereo mix. If you go to the link above, you can access the 360 site via a link below. I'm curious on how they achieve the illusion on the vertical axis.

I'm aware of the use of phase trickery to create a soundstage left and right. . .but again, how do they do height?
