On today’s date in 1910, Gustav Mahler conducted the New York Philharmonic in a concert billed as “the first of a series arranged in chronological sequence, comprising the most famous composers from the period of Bach to the present day.”

Mahler’s program included works of Handel, Rameau, Gretry and Haydn, and opened with his own arrangement of music from Bach’s Orchestral Suites.

Now, Bach’s music had been appearing on Philharmonic programs for decades, but some were shocked to see how Mahler presented it. Rather than standing in front of the orchestra with his baton, Mahler led the orchestra seated at the keyboard of a “Bach-Klavier” (a Steinway piano whose action had been tinkered with to make it sound more like a harpsichord). THAT bit of “historically informed performance” was something brand new back then.

In a letter to a friend back in Europe, Mahler wrote: “I had great fun recently with a Bach concert, for which I worked out the basso continuo conducting and improvising quite in the style of the old masters … This produced a number of surprises for me – and also for the audience. It was as though a floodlight had been turned on to this long-buried literature.”
