West Side Story is a musical with a book by Arthur Laurents, music by Leonard Bernstein, lyrics by Stephen Sondheim and conception and choreography by Jerome Robbins. It was inspired by William Shakespeare's play Romeo and Juliet. The story is set in the Upper West Side neighborhood in New York City in the mid 1950s, an ethnic, blue-collar neighborhood (in the early 1960s, much of the neighborhood was cleared in an urban renewal project for the Lincoln Center, which changed the neighborhood's character). The musical explores the rivalry between the Jets and the Sharks, two teenage street gangs of different ethnic backgrounds.
