Beautiful tension in the intro. Drums @ :59 don't seem to mesh as well when first introduced, section after that (1:34-ish) is excellent.
The loop works well.
To clarify on that bit about the drums @ 59, they still felt like part of the piece, but whereas everything else weaves through itself, the drums at that point *and only at that point* felt a bit dissociated.
Solid 4.
