The Bolt, op. 27a

The Bolt (Russian: Болт), Op. 27, is a ballet music score written by Dmitri Shostakovich between 1930 and 1931 to a libretto by Victor Smirnov. The humorous and satirical full-length ballet in three acts and seven scenes was choreographed by Fyodor Lopukhov and premiered on 8 April 1931 at the State Academic Theatre of Opera and Ballet in Leningrad. It was not performed again until 2005, when a two-act choreography by Alexei Ratmansky was performed at the Bolshoi Theatre in Moscow.
