Is that a trombone in back? Love the brass, love the slow build, the vocoder's cool too though a little hard to hear - if it's intended that you should - the lyrics. It's a spacey; atmospheric kind of trip when that kicks in...
I do love the build, and how it takes some time for it to start getting there, but there... it doesn't feel like it really does. It stays on the verge of building. In the end... I'm left a little disappointed.
Maybe the volume could gradually increase it builds too, more than it already does, or there'd just be a bit more you could add to it all... it's an awesome start. Atmospheric.
IMO just not all the way there. Not as conclusive as it could be.
