What hits me about it is how similar the sense of rhythm is to that of liturgical chant. Things happen at the "right" time, it's not arbitrary, but it's not a priori precise either. Phrases can be as long as they "need to" be and other parts of the music change to accommodate them. It's not fixed to any sort of rhythmical grid and would be extremely difficult to annotate accurately & usefully, but it still has an order in time. Hard to describe but I recognize the feel of it from chant. On the surface it sounds like jazz but jazz has a very different feel to it rhythmically. Phrases expand and contract but through the mechanism of swing. The speed and swing might change but you can always feel the underlying pulse.
