It begins like an episode of “CSI,” or perhaps a modern-day version of “The Phantom of the Opera,” set in the lower depths of a Paris concert hall. A camera pans down a darkened corridor, followed by the sound of footsteps echoing in the background. The suspense builds as the action moves up a flight of stairs as a mysterious pounding reverberates through the air. Suddenly, the camera swoops in for a close-up of a phantom figure, crouching, hovering, seemingly ready to pounce … but wait, it’s David Herbert, principal timpanist of the Chicago Symphony Orchestra, backstage at the Philharmonie de Paris. No crime scene here. He’s tuning his kettle drums ahead of a rehearsal on the CSO’s European tour.
