There is a whole other page Bix wrote that isn’t in the recording, probably due to time constraints. The omitted section is slower, marked tranquil as I remember. You can get the music online. It takes a good pianist with tenths to manage it.
I think I saw someone describe this as Debussy meets Duke. Quite a good description. I suspect Bix had a mind that never stopped thinking about music. A complex genius for sure.
