Gosh, am I lame, Fabio. I had to read that five times
before I "got it".
Arvid says he's addled -- but I think I've got him beat.
After listening to "Spheres" a few times I just couldn't help listening to "Persistence of Vision" a few times. As the others have said - Great! Really enjoyed it. I look to be hearing it for a long time.
kind comments -- and endurance in listening... lol!
Spheres and Persistence are, of course, related; with a
third sister-piece to come along, eventually.
All the best,
