I like the continuous building through repetition, like wings beating in the firmament, because in the excesses the soul overflows and becomes available. Almost, that is, as is the nature of the soul.
In a most strange synchronicity, I just finished a little clip of Niagara Falls and your No 7 is just what I was looking for -listened to Jarrett on the way to the Falls and I hear echoes here- and the length of my clip and your cut are virtually exact.
If you like, I can send you the clip with your music, which you can use however you wish. Though I will probably add a poem to my version and upload that.
