Scrappy, yes. The conductor is about the least sympathetic Rachmaninoff conductor I have heard.
Thrilling?
Hmmmmmmm.
There is nothing thrilling about the recording, which sounds to me as though the guilty recorder forgot to turn on his Dolby B when he transcribed it to digital. The piano sounds for all the world like an amplified xylophone. Appalling would be my word for it. Hardly thrilling. One could also say painful.
Presumably the BBC has passed on this "gem" for reasons of sound. Ogdon also doesn't seem as home in this concerto as he is in No. 2. It happens, I guess.
All in all this does little credit to Ogdon's memory. Best buried. A clear example of a recording which should never be disseminated.
