I echo Mario! Excellent execution of your concept. I've thought about doing this also, but with bossa guitar tracks. The more I thought about it, the more I considered how many iterations would be necessary to get just the right sequence of background guitar phrases to be satisfying. Kudo's to you for putting in the work, being patient, and having good discrimination and judgement about how to "knit" together all the iterative phrases to get to this. Really shows that, hidden in BIAB's RT"s there is real gold!

I think that the 'piano' portion of the track shows how difficult this concept can be to execute--I don't think that the piano RT's gave you as much of what you were looking for compared to the guitar.

The slow building up of the track is an example of understanding the 'architecture' of the track as it moves through time.

Thanks for this contribution, loved it!
