Hello, Tom

Very excellent and wonderful arrangement.
Anticipation by Rhode piano, acoustic piano used for the modulation following it, and high strings in the background, everything is wonderful.
As david says, truly interesting key changes in various parts.
It starts with Cminor key and eventually becomes C # minor key, but unless we listen carefully we will not notice it,
I feel the influence of Tom Jobin in your way to use Alto flute.
And I also feel Tango and Cuban Bolero in this tune.
Enjoyed my listen a lot.

Best regards.
