<P0-S0> Spartacus (Russian: «Спартак», "Spartak" ) is a ballet by Aram Khachaturian (1903–1978). <P0-S1>  The ballet received its first staging at the Bolshoi Theatre, Moscow in 1958, choreographed by Igor Moiseyev; however it was the 1968 production, choreographed by Yury Grigorovich, which achieved the greatest acclaim for the ballet. <P0-S2>  The work follows the exploits of Spartacus, the leader of the slave uprising against the Romans known as the Third Servile War, although the ballet's storyline takes considerable liberties with the historical record. <P0-S3>  Khachaturian composed Spartacus in 1954, and was awarded a Lenin Prize for the composition that same year. <P0-S4>  It was first staged, with choreography by Leonid Yakobson, in Leningrad 1956, but only with qualified success since Yakobson abandoned conventional "pointe" in his choreography. <P0-S5>  It remains one of Khachaturian's best known works and is prominent within the repertoires of the Bolshoi Theatre and other ballet companies in Russia and the former Soviet Union. <SEP> <P1-S0> John Clifford, born June 12th is the founder / artistic director of the original Los Angeles Ballet (1974–1985), and the chamber sized touring ensemble, Ballet of Los Angeles (1988–1991) and the creator of “CASABLANCA, THE DANCE” produced by Warner Bros. <P1-S1>  Theatre Ventures, Inc.
