Hair: The American Tribal Love-Rock Musical is a rock musical with a book and lyrics by James Rado and Gerome Ragni and music by Galt MacDermot.  A product of the hippie counterculture and sexual revolution of the late 1960s, several of its songs became anthems of the anti-Vietnam War peace movement.  The musical's profanity, its depiction of the use of illegal drugs, its treatment of sexuality, its irreverence for the American flag, and its nude scene caused much comment and controversy.  The musical broke new ground in musical theatre by defining the genre of "rock musical", using a racially integrated cast, and inviting the audience onstage for a "Be-In" finale. A rock musical is a musical theatre work with rock music.  The genre of rock musical may overlap somewhat with album musicals, concept albums and song cycles, as they sometimes tell a story through the rock music, and some album musicals and concept albums become rock musicals.  Notable examples of rock musicals include "Next to Normal", "Spring Awakening", "Rent", "Grease", and "Hair".  The Who's "Tommy" and other rock operas are sometimes presented on stage as a musical.
