At first glance, it depends upon one's commitment to Shabbat.
From an Orthodox perspective, all Jewish souls are already bound by an oath at Mt. Sinai to keep the Shabbat. The only exemptions that come to mind would be in cases of life and death - EG Medical or Military Emergencies.
An Orthodox role model may be found in the great singer and cantor -Dudu Ficher
Dudu Fisher - Wikipedia, the free encyclopedia
«He played the role on New York's Broadway during the winter of 1993-1994, and later at London's West End, where he was invited to perform before Queen Elizabeth II. At both venues, Fisher was the first performer excused from Friday night and Saturday performances, as he is an Orthodox Jew and was not able to perform because of the Sabbath.»

----------------------
In the ideal situation, commitment to Shabbat trumps commitment to perform.
I'm not clear as to the nature of the performance. Possibly some loopholes exist that would allow one to perform without violating the core 39 Labors prohibited on Shabbat. And so, a consultation with a highly qualified rabbi might find just a "loophole".
That said, I would not recommend that path for any committed Jew. Even if technically feasible, it would
violate many Shabbat principles, etc. that go beyond the core prohibitions.

Don’t Make Assumptions, rather
find the courage to ask questions and communicate with others as clearly as you can, in order to avoid misunderstandings. This can completely transform your life.
