West Side Story is probably Bernstein's masterpiece .. Ever since the highly favorable critical and audience reception at New York's Winter Garner Theatre on Broadway, September 26, 1957, and the phenomenal success of Robert Wise's film adaptation in 1961, this contemporary urban version of Romeo and Juliet has never ceased to move spectators and fill them with enthusiasm.
It was Bernstein who asked Irwin Kostal ( the original orchestrator with Sid Ramin of West Side Story) to produce an arrangement for the duo-pianists Katia and Marielle Labèque. This suite of 17 pieces is the only approved and authorized version for two pianos and percussion by Leonard Bernstein himself .It includes an assortment of dances and songs, which appear in a new light. Thanks to his perfect knowledge of the score, Kostal succeeds in giving his small ensemble an orchestral fullness. The seeming monochromy of the two pianos, far from making the music dull, allows us to appreciate a harmonic language that is simple yet quite subtle, in the service of the composer's enormous talents as a melodist. Deprived of the lyric dimension provided by the voices, the songs unfold their phrases with unsuspected naturalness and authenticity.
(August 25, 1918 – October 14, 1990)
Bernstein told Rolling Stone:
'Everyone told us that [West Side Story] was an impossible project... And we were told no one was going to be able to sing augmented fourths, as with 'Ma-ri-a'... Also, they said the score was too rangy for pop music... Besides, who wanted to see a show in which the first-act curtain comes down on two dead bodies lying on the stage?... And then we had the really tough problem of casting it, because the characters had to be able not only to sing but dance and act and be taken for teenagers. Ultimately, some of the cast were teenagers, some were 21, some were 30 but looked 16. Some were wonderful singers but couldn't dance very well, or vice versa ... and if they could do both, they couldn't act.
