Anatoly Lyadov
Rusalka ( ) is an opera in four acts, six tableaux, by Alexander Dargomyzhsky, composed during 1848-1855. The Russian libretto was adapted by the composer from Aleksandr Pushkin's incomplete dramatic poem of the same name. It premiered on 4 May 1856 (Old Style) at the Theatre-circus, conducted by Konstantin Lyadov (father of Anatoly Lyadov), choreographed by Marius Petipa and Nikolay Goltz, but was badly received predominantly by the aristocracy.
