At first it sounded like a movie theme from the '70s. Then it developed a certain hypnotic quality that fits, I guess, its New Age intentions. Once you had established the pattern, then came the welcome tempo change, complemented by the nicely done rit. at the end.
I don't really know anything about New Age aesthetics, but the piece was very nice. It was coherent, and it went somewhere. About time that the repetition was going on a bit long for this non-New-Age listener, you sped up.
As for how icicles can dance, I think one way is through transmitting, refracting, and reflecting ever-changing light.
