Since this was extracted from a mix, there's overlap with the Chems' "Golden Path - ravehell dub" for a bit... as awesome as the mixed portion sounds, all acid squelchey, i'm thinking it's not fully UW until ~0:50 into the extract.
When i played this in the AM, i thought, "dang, UW's gone acid!" Not that that's a bad thing, but just something to be aware of, the effect of mixing with the former track.
It's still wonderful, though!
