Bass William Thomas will no longer perform the final two performances of the “Les Troyens” tour.

The bass who was performing the role of Narbal will no longer perform at the Berlin Philharmonic Hall on Sept. 1 nor at the BBC Proms on Sept. 3. As a result, he will be replaced by Alex Rosen, who was already performing the roles of The Ghost of Hector and Second Sentry in the tour.

The news comes days after Sir John Eliot Gardiner withdrew from the tour after having slapped and punched Thomas during a performance at the Berlioz Festival. The incident caused an international scandal and forced Gardiner to apologize for his actions.

Thomas’ management released a statement that confirmed the incident and said, “We can confirm that an incident took place after Tuesday’s performance of Berlioz’s ‘Les Troyens’ with the Orchestre Révolutionnaire et Romantique and Monteverdi Choir at La Côte-Saint-André. Bass William Thomas is looking forward to continuing the tour with performances in Salzburg, Versailles, Berlin, and at the BBC Proms, and will not be making a statement at this time. All musicians deserve the right to practice their art in an environment free from abuse or physical harm.”

Thomas next performs at the Teatro alla Scala in a production of “Peter Grimes.”
