Leonard Bernstein and Jerome Robbins shared mutual desires to innovate and create in their individual fields and to create truly ‘American’ art of the twentieth century. Their collaborations for ballet (Fancy Free, On the Town, Facsimile, Age of Anxiety, Dybbuk) and musical theatre and film (West Side Story) propelled each into defining their specific style and artistic voices. Their aim to synthesize classical, symphonic aesthetics with rhythms and movements of Black and Latinx vernacular dance and music; their mutual interest in translating character, intention, emotion, mood, and narrative circumstances through non-textual mediums; and their active integration of music and movement in the creative process cinched their artistic connection. Even after the two went their separate ways, their legacies are forever entwined.
