A Conductor’s Once and Future Orchestras Present Dueling Concerts

Marten Root, a flutist specializing in historical instruments, has played under the conductor John Eliot Gardiner for over 35 years, and considers him a profoundly intelligent and honest musician.

Root, 68, has also had severe enough verbal disagreements with Gardiner, 81, that he twice temporarily quit working with him. The reasons were “incidents which happen if you’re a flute player in an orchestra,” Root said in a video interview. “You’re the top of the score. You’re always in the line of fire.”

Both times, he returned. Playing under Gardiner, an eminent performer of Baroque music who has recorded every single Bach cantata, was “no easy job to do,” Root said, “but basically, I decided to go back to the orchestra twice, because it’s musically more than worth it.”

In August last year, Gardiner struck the singer William Thomas following a performance of the opera “Les Troyens” in France. Gardiner apologized and announced that he was temporarily withdrawing from all conducting.

Now, Gardiner has returned — but not with his old organization, Monteverdi Choir & Orchestras, which didn’t want him back. Instead, Gardiner has just completed a tour with a new ensemble he founded, the Constellation Choir & Orchestra.

The two groups almost collided recently, playing nearly identical concerts at the Elbphilharmonie in Hamburg, Germany, on Dec. 7 and 14. Heard so closely together, the performances offered an unusual glimpse of what’s ahead for Gardiner’s once and future ensembles. Although the concerts looked similar on paper, they sounded strikingly different.
