Most Sublime Beethoven Symphony

My recommendations are:

For a new perspective listen to John Elliot Gardiner. Great sound, new scores prepared from from Beethoven's manuscripts, wonderful playing and conducting, and a true "classical" sound, authentic to the period.

For simplay magical playing listen to any and all of the Fritz Reiner/Chicago Symphone recordings. The playing is astonishing in its tightness and rhythmic drive. Some of the symphonies are available as XRCD discs and sound as good as I've heard.

For historical perspective the recordings by Klemperor and Furtwangler are wonderful. I always loved hearing Karajan live but the recordings do not sound good to me.

as for the Emperor Concerto, you will be blown away by Horowitz and Reiner on RCA (yes Horowitz); simply a joy. And every piano player loves it and wishes they could play is so effortlessly. It is Horowitz in his prime, circa 1955.

For performances that are both vigorous and rigorous, you can always count on Solti/Chicago. The miking/mixing isn't always the greatest, though. Sometimes you have to listen around the bonehead engineers.

I have about 8 different recordings of the 6th Symphony
(including the one by Reiner). The one I like best is the one by Karl Boehm with the Berliners; the Karajan is too fast. On the other hand I don't like Boehm's 5th, but like
Karajan's/ And, Karajan's 1962 recording of the 9th is the
best I've heard. Caveat: I'm not a musicologist or guru; I just know what I like.

Also listen to the Pollini/Boehm 4th Piano Concerto.

The Triple Concerto is a truly wonderful piece of music. I have the recording by Anda/Fournier///Can't remember the rest, but if you're interested, can send you the LP info.

Beethovens music is the only music that has moved to think that God was holding the composition pen directly as the notes were being put down. It is amazing to think that Beethoven reportedly labored over his compositions. You would think that his creations came forth with the ease which Bach, Teleman and Mozart displayed when composing.

I agree with the Kleiber and Gardiner rec's as being the most inspirational performances and from different performing practices to boot.

Karl Boehm's performance of the 6th is one of my favorites too!!
