One of my absolute favourite pieces of music - heart-burstingly thrilling if performed well. I started a post a few months ago on posters recommended versions as I felt that I needed a more modern recording than Launy Grøndahl, whom I regard as hors concours in this symphony. I don't know quite what it is about his recording that makes it so special - his choice of tempi? the timbre of the orchestra? the balance of instruments? Whatever it is, my somewhat obsessive listening to (and collection of) no fewer than 14 of the recordings listed above, plus Gibson, Karajan, Thomas Jensen, Igor Markevich etc, failed to reveal a recording which has the same effect. I'm not sure how easy it is to get hold of the Dutton re-issue rather than an MP3 download but if ever a recording deserved the accolade, "Great Recording of the Century", it is surely it.
Otherwise, I'll be interested in David Fanning's views. Incidentally, has Thomas Dausgaard recorded the symphonies? I had convinced myself that the Da Capo slipcase with 3 CDs of the symphonies which I have mysteriously lost contained recordings by him but I now think that it was probably the recordings by Michael Schønwandt and I got my Danish conductors a bit mixed up. The recent Da Capo box contains two different Schønwandt cycles - the original as issued by Da Capo then Naxos and which is on CD - and another live cycle, recorded in 2000, which is on DVD. It also contains Dausgaard's standout SACD of Nielsen orchestral works (about which David Fanning raved with a good deal of justification in The Gramophone). My vote would probably go to Davis, which is almost as thrilling as Grøndahl - and my candidates for the black spot would certainly include Salonen and Martinon, who conducts it slickly but with little feeling for the music.
Oops, apologies for going all train-spotter
