In this expansion of her doctoral dissertation, Wells (Mount Allison Univ., Canada) explores West Side Story in terms of musical and cultural expression. She begins with an account of the show from its inception to its Broadway opening. She next considers Leonard Bernstein's musical score and then discusses ethnic (primarily Hispanic) issues, gender relationships, and juvenile delinquency as revealed in the show. Finally, she writes of how perceptions of the work have changed over time. Wells's approach is broader than Nigel Simeone's in Leonard Bernstein: West Side Story (CH, Jun'10, 47-5555), which emphasizes the composer's contribution; thus the two works complement each other well. Both join Keith Garebian's The Making of West Side Story (1995) in providing in-depth treatment of this major Broadway musical. Numerous illustrations and musical examples enhance the text. Wells demonstrates command of the subject through her excellent documentation and bibliography. However, neither Wells nor Simeone provides major discussion of the film made from the musical, a subject that cries out for consideration. Summing Up: Recommended.
