Yup, that's the page that i gathered that info. But they are known recordings, have they been issued before, has anyone heard them or is this the first time they're available?
I'd be most interested in Arrau and Freire with the concerto. Seeing it played with resources available like that is fascinating.
Recently my big discovery is Jack Gibbons playing the concerto. The he plays it with greater technical aplomb than Ogdon is impossible to believe, but he did it and live at that. I knew of his recordings before, not sure why i didn't listen to them, probably because i assumed he'd be on Ronald Smith's level. Certainly i respect Smith's work, but the tempos are not right. But then i found the performances of Gibbons on youtube, that changed a lot.
