Alexander Nikolayevich Serov (Russian: Алекса́ндр Никола́евич Серо́в , Saint Petersburg, 23 January [O.S. 11 January] 1820 – Saint Petersburg, 1 February [O.S. 20 January] 1871 ) was a Russian composer and music critic.
 He is notable as one of the most important music critics in Russia during the 1850s and 1860s and as the most significant Russian composer in the period between Dargomyzhsky's "Rusalka" and the works of Rimsky-Korsakov, Mussorgsky, and Tchaikovsky.

Carmen Suite is a one-act ballet created in 1967 by Cuban choreographer Alberto Alonso to music by Russian composer Rodion Shchedrin for his wife, prima ballerina assoluta Maya Plisetskaya.
 The premiere took place on 20 April 1967 at the Bolshoi Theatre, Moscow.
 The music, taken from the opera "Carmen" by Georges Bizet and arranged for strings and percussion, is not a 19th-century pastiche but rather "a creative meeting of the minds," as Shchedrin put it, with Bizet's melodies reclothed in a variety of fresh instrumental colors (including the frequent use of percussion), set to new rhythms and often phrased with a great deal of sly wit.
 Initially banned by the Soviet hierarchy as "disrespectful" to the opera for precisely these qualities, the ballet has since become Shchedrin's best-known work and has remained popular in the West for what reviewer James Sanderson calls "an iconoclastic but highly entertaining retelling of Bizet's opera."
Kashchey the Deathless (Russian: Кащей бессмертный , "Kashchey bessmertnïy"), Kashchey the Immortal, is a one-act opera in three scenes (styled a "little autumnal fairy tale") by Nikolai Rimsky-Korsakov.

 A similar fairy tale was also used by Igor Stravinsky (Rimsky-Korsakov's pupil) and Michel Fokine to create their iconic ballet, "The Firebird".
