It's interesting this came up, as I am reading some early-90s tomes with a general focus on San Fran and "house music" and the thing that keeps coming up is 120 bpm = heartbeat in the womb... turn the room into a womb, and all this. It's also amusing that the tone of the excepts on the speed of house music keeps defending how "fast" it is i.e. "it may seem fast but..." and here I am thinking of 150bpm killllargh. Here I thought that 145 was double the healthy heartbeat, so one beat is <in> and the other beat is <out> with the heart... still, to this day, I remember the entrancing effects of Acupuncture's Reality Conflict on V/A Psybration with the breathing atmospheres and just how much of a trance you can get into when you're surrounded by that, out at an event, dancing your ass off. There is a fractal feedback loop involving the physical exertion of dancing, an endorphin rush, and pushing your heart rate up to the speed of the music. I don't think you can really say it's not 'trance' just because it isn't slow and repetative. Higher more active music can be entrancing too, depending on the specific quality of the material at hand.
