I bought the Karajan 1963 set when it first came out, when I was a freshman in college....
...I checked and I have 3 different Furtwangler 9ths - from 1954 and 1951, both with Schwarzkopf singing the soprano role (I am guessing her husband or husband to be Walter Legge may have had something to do with the recording) and a war time recording from Berlin - in front of Hitler as I remember...
PS. As a junior, we had a sophomore, Bob Levin, living across the hall. He had a piano in his room and would play the 32 Beethoven Piano Sonatas straight through. He later went on to become an accomplished fortepiano player, with quite a few recordings, as well as a professor at the college.
Great stories...which of the Furtwangler's 9s do you like best?
