I have a question: Is that orchestra admitted to other international gigs without problem? I don't mean to EU countries; presumably they have reciprocal arrangements. But to Russia or to anywhere in Africa or to Asia?

I hadn't realized that there are 100 + members of the orchestra. Obviously it would be difficult to process that many in one day.

On the other hand, if each member of the orchestra were made responsible for getting each individual visa - and a number of them doubled up in travel - it would seem doable.
