Before COVID, my wife and I attended a lot of classical music concerts - up to 70 a year, including around 25 or more during our annual visits to London and environs. They varied from solo piano recitals, to chamber music to orchestral concerts and operas. For major orchestras these days, it is unusual for the music director (like Dudamel with the LAPhil) to conduct more than half the concerts during a season. We would often see MTT conduct the London Symphony in London during June, when he typically came to conduct a few concerts. He was the principal guest conductor of the LSO at the same time he was MD of the San Francisco SO. We also saw Dudamel in Berkeley conducting his Venezuelan Youth Orchestra at the same time he was MD at the LA Phil.
Back in the day, I started going to the SFS when I was a grad student at Berkeley in the late '60's. They had a special deal for students and I went to the entire series in quite decent seats for a bargain price. The famed Austrian conductor Joseph Krips was the MD then (followed by Ozawa) and Krips conducted the vast majority of the concerts. But that was then, and the SFS was not at the same level as it is now and I don't think MD's of major orchestras had two or three jobs, with jets taking them around the world to conduct.
