Query: their best

I fully agree with the other reviewer. Actually, I have little to add to his comments, except to say that of Trance Mission's several albums, this is clearly their best, and the best starting point for appreciating their music. One thing I might add is to note that for a group that falls pretty squarely into the techno-ambient mold, they produce a lot of drama. This is not at all sterile atmospheric stuff, but music with a lot of grit and bite.
