I was tagging some albums on Picard related to this release group: https://musicbrainz.org/release-group/0a1eb1b0-5f83-3fcc-8e7e-811ec4f60d5d. The title of the release group indicates that it is for releases of the Ashkenazy orchestral version. As can be seen here, the piano recital and the orchestral version were both recorded in 1982. This release also belongs in the same release group.
However there is a third release associated with it, corresponding to this release where both the piano solo version and the orchestral version were performed in 1967. Moreover, this release was based on Ravel’s orchestration, and was conducted by Zubin Mehta. This definitely belongs in a different release group. The evidence of the recording dates here, at discogs
I tried to fix things myself, but this requires some rather drastic changes. I’m rather new to editing, and I’m afraid I’ll mangle things badly if I try to fix it. Can one of the experienced editors please fix it? I can provide all the technical info you need.
