"Gilbert Edmund Kaplan" is an American businessman, former journalist and amateur Conducting/conductor.

He founded the magazine Institutional Investor in 1967. He was publisher of the magazine until 1990, and editor-in-chief for three more years, although he sold it in 1987 for $72 million. He then concentrated on conducting, hiring Avery Fisher Hall in New York for his debut in 1982. He set up the Kaplan Foundation dedicated to Gustav Mahler. After personal research, he has twice recorded Mahler's Symphony No. 2 (Mahler)/Second Symphony: with the London Symphony Orchestra in 1987, and with the Vienna Philharmonic in 2002. He has bought the autograph of Mahler's score of this symphony and commissioned a facsimile edition of the score. He is co-editor of the new critical edition of the Second Symphony as part of the Complete Critical Edition of Mahler's works, to appear soon. He is a member of faculty of the Juilliard School (Evening Division).

Mahler's Second Symphony is the only complete work he conducts, although he has also recorded the Adagietto (Mahler)/Adagietto from Mahler's Symphony No. 5 (Mahler)/Symphony No. 5.

More Gilbert Kaplan on Wikipedia.

There were mistakes in the score and parts in practically every category, including wrong tempo indications and inaccurate dynamics.

I now have 20 years experience conducting Mahler's Second Symphony and studying all of Mahler's music. About the same amount of time I concentrated on finance and the media. I suppose I know more about Mahler now than I know about finance. But someone else would have to decide whether I was a better executive or conductor.
