It has a 'key' it's just not standard. It doesn't matter though.
What it does is make use of specific scales, or one scale, in particular, the minor scale or maybe one of it's variants.
The problem is actually ... they stay in that one scale, forever. This is a limitation of this music.
This music is: take a scale, and have someone play a very long, intuitive solo overtop in that one key, effectively one chord. The structure is really quite limited unfortunately.
