The history of Mussorgsky’s only completed opera is a bit(?) complicated. His first version (1869) was rejected by the powers that be because there were no major female roles in the work; so the composer set to and, by 1872, had produced a version complete not only with a significant part (Marina) for mezzo-soprano but additionly several other female-voiced characters had been given extra material. This version passed muster and was duly performed – but in a very much butchered version – in the Mariinsky Theatre in January 1874.
But the story doesn’t end there: after the composer’s death, Rimsky-Korsakov, feeling that the orchestration could be improved and that some of the harmonic ‘infelicities’ of the score should be ironed out, produced, in 1896 and 1908 respectively, not one but two ‘corrected’, re-vamped and re-orchestrated versions of the work both of which omitted some of Mussorgsky’s original music, and it’s the 1908 Rimsky-Korsakov revision that was performed for most of the twentieth century.
Then there’s a Shostakovich version based on the original vocal score…
