ABOUT ROCK OPERA

That rock became part of musical theater should not surprise us. Both share not only a certain underground character in their beginnings but also the heritage of Afro rhythms and an aesthetic transgression that little by little gave characteristic color and shape to their structure. 
However, the traditional musical comedy told its stories for a long time from jazz and symphonic music with permanent references to its grandmother: Italian opera.
Thus, rock has been as fickle as the operatic forms, referring to a variety of genres and subgenres so diverse that their musical specificities are difficult to define. However, these were consolidated from 1950, when some of its manifestations known as rock and roll became popular. Already in the sixties, rock music was associated with the identity of the protest song, rebelling against social and political norms.
The musical comedy was no stranger to this and was updated to speak to a complex society. With musicals as controversial and exciting as "Hair" or "Jesus Christ Superstar", musical theater was building a new discourse, making clear its committed insertion in a context that -through art- allowed reflection, crisis and finding motivations for change the faces of reality.
