Recommend Classical Piano LP's

Alfred Cortot playing Chopin's fourteen waltzes.
It was originally put out by Angel in 1957 on their Great Recordings of the Century series, with a nice booklet as well. These are from a 1934 original recording so the sound is not up to current standards but the playing is unrivalled in my opinion. It was later redone by Seraphim sometime after his death in 1962.

Would add Rubinstein's original non-digital version of the Nocturnes on RCA shaded dog. Having listened to them and compared them to the digitally remastered version they are far superior.
