Klemperer often used very brisk tempi in his early recordings. My mom was a teenager when he conducted the LA Phil in the late 1930s, attended every concert she could, and remarked on the "high energy". That he evolved into such a deeply introspective musician is remarkable. His Bruckner 6th was my favorite performance, 3 minutes longer than most and the deeply satisfying. Then I heard Celibidache's, even slower by an additional 4 minutes.
Los Angeles always had great instrumentalists, especially after the mass exodus from Nazi Germany. Hollywood, then featuring orchestral soundtracks, offered many jobs and top pay. The Philharmonic was always a potentially truly great orchestra, but for some reason never had a permanent conductor of immense stature. I saw Solti conduct several times in the ’60s, when I was a teenager. He agreed to be main conductor, and I attended his first concert as new leader. Before the program started, the Manager came onstage and announced that Solti had cancelled. However, a new conductor would step in — Zubin Mehta. Beethoven’s 7th was the main piece.
Solti was apparently so insulted he cancelled his contract, and Mehta inherited the podium.
I veered a bit off-topic, sorry — this is about Otto.
