Water music, essentially. Some of the music is wet, liquid - some dry as a stone. The pulse like a river - straight, steady, but with abrupt twists, turns. You hear the same music 3 times (but never the same - can't step in the same stream twice…) followed by an extended afterthought.

"Upon those that step into the same rivers different and different waters flow…
They scatter and…gather…come together and flow away…approach and depart."
