I've owned this recording since it was first released on a 2-LP set in 1981, where each movement occupies one whole side. It was accompanied by a lavish book that included a write-up of Bohm as well as a calendar listing all the important events and recordings of his life. It was noted that Bohm considered Berry, Domingo, Fassbaender and Norman to be the ideal soloists for this work at that time, together with his beloved VPO and the Concert Association Chorus. Later, in 1986, this recording was produced on a double CD set, together with the original LP artwork and essays, coupled with his famous 1971 recording of the "Pastoral", and it was one of the first Beethoven Ninths in DGG's CD catalogue then. The current remastered single CD on the "Masters" series has better sound, and is preferable, although all the original sleevenotes have been deleted.
Although I own about 20 different recordings of the Ninth, I regard this as one of the most important. True, the tempi are slow, but Bohm does not falter; neither is he sluggish. In spite of the slow tempi, the concentration and playing of the VPO, chorus and soloists are faultless, and there is a wonderful sense of a "live" occasion which one seldom perceive from studio recordings. It is as if everyone knew that this would be Bohm's last recording and that he would be dead within months. Most of the other reviewers here who had been positive about this recording have listed its outstanding merits, which I shall not repeat. Confirmation that Bohm had a clear vision of the work, and knew what he was doing, came from no less than Placido Domingo himself. In his autobiography, Domingo noted that, in the alla turcica section of the 4th movement which features the tenor voice, Bohm set the "ideal tempo, unlike other conductors" (Domingo's own words). It was also during this recording that Bohm presented Domingo with his own autographed copy of the score, and Domingo would later regret that he didn't have the chance to collaborate with Bohm in any operatic work. That this recording is excellent is also evident from the Penguin Guide, which has consistently given it 3 stars (out of 3) in every edition since 1981 in spite of renewed competition from many other recordings since that time.
In summary, this is not a performance of the Ninth that you can listen to as and when you like (or as background music !!). It commands your every attention. You should only listen to this on a day when you feel like listening to a performance of the Ninth, and you have about 90 minutes to spare where you are 100% certain that you'll not be disturbed. You'll be amply rewarded, and each listening brings forth fresh revelations about the work. As some reviewers have noted elewhere, once you have experienced the wisdom of Bohm in his music-making, be it Beethoven, Mozart or Strauss, you'll find it hard to listen to other so-called superstar conductors. As the author of the original sleevenote essay noted, "the very essence has been grasped".
