Joãosinho Trinta was a Brazilian director of parades for Samba Schools in Rio de Janeiro Brazil during Carnival.
Trinta is credited in changing the aesthetics of the main carnival Parade in Rio during the 1980s. Trinta introduced a new standard for the costumes and enlarged the scenery, creating new dimensions of visual impact. The local press gave him large space in the media as a public person in Brazil, after his reply to critics: "Only intellectuals like poverty, the poor people like luxury."
Trinta's style was copied by competing Schools of Samba. In 1989 he caused another media impact through the parade, when he called attention to the operatic elements of Carnival and brought to the Avenue Marques de Sapucai a parade that was void of any shining costumes and used an aesthetic of trash to print a dark image into the history of the event. The parade of Samba School Beija Flor that year marks a historic shift in the evolution of the genre.
