Behold the beauty of the octatonic scale, mode 2 in Messiaen's modes of limited transposition. Yet you do not find it totally binding as you move around in a Scriabinesque song and brevity making me wonder if anything comes before and after as a set. I especially like the section from about 35 seconds to 46 seconds...maybe the heart of the piece, a beautiful harmonic climax and change out of an older world, almost Faure's.
I love hearing new music.
