unique recordings from Philips Great pianists of 20th cent?

I just found out that Yudina’s Goldberg variation is only available on the Philips infamous series (and what a recording it is), it wasn’t even available on vista vera legacy series

anyone knows any other unique recordings from the philips series?

Ogdon’s Alkan Concerto is pretty hard to find elsewhere.

I think I read somewhere that Curzon’s Schubert Impromptus are only available in that edition. (Not a fan of Curzon, though some of his Schubert is not bad)
