My next Rimsky-Korsakov work I'm reviewing is the 'Antar' which is usually mistakenly called his second symphony. From what I can tell are there three versions? Has anyone listened to all three? I don't have the original but I do have the second and third versions. My second version I think is with Maazel and the Pittsburgh. The third version I have several versions. Who is the resident expert on this unsung work? I say that because Scheherazade is performed 100-1 over this neglected wonderful work.

If I remember rightly, there are
four versions of "Antar" - the original, the revision of 1875, the 1897 one (composer's "definitive" final thoughts) and the 1903 score, a mixture of the 1875 and 1897 versions due to the publisher deciding it would be too expensive to bring out the 1897 version.
I don't know about recordings, pretty sure the original version hasn't been recorded and I read somewhere that the majority of conductors use the 1903 score in the mistaken belief that this is the final, definitive version rather than the compromise it actually is.
As for the first symphony, a hearing of the original score would have curiosity value but is a recording and the time/expense that involves really worthwhile? Rimsky-Korsakov was quite open about the limits of his knowledge in the 1860s and saw the revision as cleaning up what his later more educated self could see as mistakes in the work and also changed the key to make the work easier to perform.
