That is pretty powerful stuff. A lot of layers. The first part of this piece is so like rain - one of my favorite sounds. I love the unpredictability of the music. It takes some serious concentration to listen to properly so I can't even imagine how challenging it is to play.
When the music transitions about 1/3 of the way in it reminds me a bit of something I saw on TV a long time ago. The TV special's music left an impression on me at the time. The dance (it's hard to remember well but I think it was ballet) was something about a puppet with broken strings. I loved the correlation of the music and the way the dancer portrayed the broken toy that was uncoordinated and uncontrolled.
P.S. I deny all accusations of car singing and want to call my lawyer. 😉
