A few years ago at a record store job I once held, a customer approached me asking for recommendations of Mahler recordings. I led him over to the composer’s section in our store and began going through several which were personal favorites. He asked if there were any integral sets of the composer’s symphonies which I could suggest. We happened to have Michael Gielen’s cycle in stock and held that one out to him.

The customer just looked at me puzzled.

“Who is he?”

I replied with a very brief summary of his life and work, adding that he was to me the greatest conductor then living.

“He can’t be that great,” this customer shot back in irritation. “I’ve never even seen him on social media.”

Requiescat in pace.
