OK, this is amazing of course, because Walt put it together. But of all the tasty elements you have going, Walt, for whatever reason this time I found myself focusing on the kick drum. It's full without being overbearing, obviously drives this piece, and just sounded perfect as a foundation.
The percussive elements you have swirling around are tasteful, and not overbearing, either!
And the vocalist, she's great, as is your mix treatment of her. Love the "telephone with cathedral reverb" effects I think I'm hearing, very cool.
cheers,
