DESCRIPTION:
Castor et Pollux (Castor and Pollux) is an opera by Jean-Philippe Rameau, first performed on 24 October 1737 at the Académie royale de musique in Paris.

The librettist was Pierre-Joseph-Justin Bernard, whose reputation as a salon poet it made. This was the third opera by Rameau and his second in the form of the tragédie en musique (if the lost Samson is discounted).

Rameau made substantial cuts, alterations and added new material to the opera for its revival in 1754. Experts still dispute which of the two versions is superior. Whatever the case.

Castor et Pollux has always been regarded as one of Rameau's finest works.
