I think Lane was cast early on as the lead in SB because of her strong technique, which is also why she was cast in Theme & Variations. She can handle technically demanding choreography, and so she has, in the past, received parts which are technically challenging.
I’m a firm believer that, no matter how talented you are when you’re young, there’s a certain amount of life experience you can’t accelerate. Misty could have done these same roles—technically—ten years ago, but she wouldn’t have been ready.
Granted, my exposure to Lane has been limited, but I've never seen or read much to suggest that Lane was an interpretive prodigy to justify an early Aurora using the same criterion.
She told the Daily Mail thatI think that the reason [it's hard for black women to break in] is the racism and not wanting to change this very traditional art form that has been successful in the way it is for so long
Since she says “reason,” singular, she seems to see the two things that follow as one and the same. In other words, traditionalists are racists. Now granted, traditionalism can be a cover for racism (among other things), but she just equates the two, plain and simple.
I think that is a stretch. "The reason is" followed by a list is a grammatical mistake I've seen regularly in writing, whether that be on message boards, blogs, or poorly copy-edited (semi)-professional writing, let alone interviews where an interviewee is responding to a question in the moment verbally.
I think the two things are linked, especially since most traditionalists -- your word, not hers -- don't go farther than "What I saw the first time" plus perhaps "What I can see on video" and don't have much of an historical or accurate view of what that tradition is or the evolution of the art form, like thinking that what the Bolshoi or Mariinsky puts on the stage in classics today is what Petipa choreographed, or that the extensions perpetrated on us by lithe white dancers in the traditional rep would be recognizable even by the generation of coaches in Moscow or St. Petersburg. "Traditionalists" can be rather selective about what they include in tradition.
