One hopes they are good musicians, but that's not the point. The director of the ETO has explained that competence was not the reason why the the musicians were replaced, it was because of their non-musical personal characteristics.Were these new musicians demonstrably better than the musicians they replaced? That's a question to which I would be interested in hearing the answer.
As I said in post #37 ...
"It might be acceptable, albeit a bit brutal, to have terminated the musicians for the reason of competency or 'artistic fit', and replaced them with 'better' musicians, but to have done so due to the musicians' race, religion/belief, marital status, sex, sexual orientation, disability, gender reassignment &cetera is abominable."
Even if the ETO maintain music standards, as I have previously said, a crack-outfit like the Sinfonia of London won't, if this approach is widened out to other orchestras.
