Man very typical David F sound for the deep stuff. Think you're onto something here. Maybe could have one more element to keep it moving some where along the line and stretch it out past that 3.00 minute marker. I'm only in the phones so can't comment on the mix really, but you always do an excellent job with that. No matter whether it's hard noises that should make your ears bleed or nice smooth stuff like this.
Always good stuff my friend. :-)
