Youtube used to have an outstanding version of Beethoven’s 9th conducted by Herbert Von Karajan. There were two parts to it, each over 30 minutes. It was pulled and I can’t find it anymore. I’d love to find it on DVD.
HVK’s 1966 Berlin Symph. performance of the 5th has just been reinstated on You Tube after an absence. I feel it is the greatest documented live musical performance in history.
