If you want to see Sandra Bae’s “musicality” just watch this arrangement and performance of Moon River.

That pretty much sums up where she is there.
I saw that; as an improviser I can respect and be awed by a technically astute performance but I am more interested in things she has perhaps not rehearsed 1000 times.
Sounds wonderful.
