Conductors may elect to restore the cuts the composer himself made in writing the 1872 version Versions in this article for more details. The 1997 Mariinsky Theatre recording under Valery Gergiev is the first and only to present the 1869 Original Version side by side with the 1872 Revised Version, and, it would seem, attempts to set a new standard for musicological authenticity. However, although it possesses many virtues, the production fails to scrupulously separate the two versions, admitting elements of the 1872 version into the 1869 recording, and failing to observe cuts the composer made in the 1872 version.
