We talked about the Bach suites in an interview almost exactly three years ago, and back then recording them was not on your mind. Why did you decide to?

That was the first season that I was doing all six suites in one go in concert, so I was living with them in a very different way, and thinking about them in a very different way. Having them flow into one another, chronologically, gave me a better perspective on them. I thought I would only record them when I was very old, and hopefully a bit wiser than I am now. Then I thought, I’m at an interesting point of my life — I have a young child — so I wanted to document this moment.

You’re far from the only the artist turning to Bach at the moment. Why is he still such a touchstone?

I think each person really listens to it with a personal take on it. I suppose that can be applied to any music, but there’s something about Bach which is so timeless, and so sublime, and so human, that it’s universally touching.
