My kind of ambient.
I love the atitude of the piece! It's like its both confident and cool- sexy; in a word. It's dark, with out being depressing. Mysterious, really.
It what most ambient doesn' do, but should: remain cool and chill, with being gimmicky or boring.
Good use on the bass, it's there, but works well with everything. Only complaint is that the ending, it kinda "harshes my mellow, man".
