That would do it!
As is often the case with classical music, we tend to prefer the first version we heard — the one that attracted us to the piece in the first place. Even though there are better recorded, and better mastered, versions of the following works, I still like to listen to these recordings that I first heard in the mid-60s: Yehudi Menuhin doing the Mendelssohn Violin Concerto; Solomon doing the Grieg Piano Concerto; and Rudolph Serkin doing Beethoven's Emperor Concerto. One of the downfalls, in a way, of repetitive listening?
P.S. I'm gonna check out the Upshaw version. Thanks!
