The words at the end of "South" are spoken by Holly Hunter in the film "The Piano" by Jane Campion:

"At night! I think of my piano in its ocean grave, and sometimes of myself floating above it. Down there everything is so still and silent that it lulls me to sleep.
[...]
There is a silence where hath been no sound /
There is a silence where no sound may be /
In the cold grave, under the deep deep sea."

Again, the last three verses are taken from the poem "Silence" by Thomas Hood (1799-1845).

this EP might be one of the best efforts done between such talented producers as those two.

4 tracks and none of them is in the same style of the other one, North is Hard-Style, South is Ambient, East is Progressive House and West is the hardest of all. i'd just have to say its Spacey-Ambient-Prog-Style.

a must have in every collectors bag!
