Having read Andrew Goldman's article, I can't help but wonder about another alleged fact, that she was born on February 2, which is also Eva Cassidy's birthday. (See Wikipedia.) I don't mean to be cynical by saying that. One gets the sense she is very much in the throes of constructing an identity, because of her age (isn't that what one's teens and 20s are about anyway?), the after-effects of her accident, and the process of unfolding her talent and discovering where it might take her.
I've read quite a lot about the development of young musicians recently, especially jazz musicians, and finding the balance between audacity and humilitywith a capacity to listen deeply to other musiciansis central to the process. Some pretense and role-playing is also probably unavoidable for most, especially if one is trying to escape certain constraints and inhibitions of one's background.
NOBODY can doubt her courage.
(PS: In this connection, see
this AAJ interview with saxophonist Myron Walden.)
