António Joaquim Rodrigues Ribeiro was a Portuguese singer and songwriter. Despite his short-lived career due to his premature death at the age of thirty-nine, using the stage name of António Variações, he became one of the most culturally significant performing artists of recent Portuguese history. His recorded works blended contemporary music genres with traditional Portuguese rhythms and melodies, creating music which for many is symbolic of the liberalization that occurred in Portuguese society after the Carnation Revolution of 1974. The original and provocative nature of his recorded works has led to him being widely recognized as one of the most innovative artists in the recent history of Portuguese popular music.
