Facing Criticism After Striking Singer, a Maestro Forms New Ensembles

The renowned conductor John Eliot Gardiner, who has faced widespread criticism since he struck a singer during a tour in France last year, announced on Monday that he had formed a new choir and orchestra as he attempts a comeback on the global stage.

Gardiner said his new ensembles, the Constellation Choir and the Constellation Orchestra, would be made up of prominent musicians and singers from across Europe and would embark on a tour in December with stops in Germany, France, Austria and Luxembourg.

“More than anything else,” Gardiner said in a statement, “I am so excited and grateful to be working with such exceptional musicians once again, not forgetting the important lessons I have learned and needed to learn from the past year.”

Gardiner, 81, a major figure in classical music, is known for founding three acclaimed period ensembles over the past six decades: the Monteverdi Choir, the English Baroque Soloists and the Orchestre Révolutionnaire et Romantique. He has released celebrated recordings, written a book about Bach and conducted at the coronation of King Charles III of Britain.

But since the incident in France, he has largely been absent from the global stage. In July, the board of the Monteverdi Choir & Orchestras, the nonprofit that oversees the three ensembles, said it had decided that Gardiner would not return to the organization. (Gardiner has sought to frame that decision as his own.)

Gardiner struck the singer, William Thomas, a rising bass from England, on the face last year after a performance of the first two acts of Berlioz’s opera “Les Troyens” at the Festival Berlioz in La Côte-St.-André. He was apparently upset that Thomas had headed the wrong way off the podium at the concert, people at the festival said at the time.
