A metaphysically-oriented friend, Chris Carmona, played a piece she had written on the piano after a meeting of our studies group. It was a very simple piece, not really more than a series of chords; but the chord progression was addictive and I loved it, and asked permission to arrange it. She calls it Altronia, after a science fiction story she'd been working on.

That chord progression turns out to be sturdy enough to carry almost anything you build on it. It lends itself equally well to a pop arrangement—as on The Man Who Still Isn't There—or to a concert arrangement, as here.
