Luiz Gonzaga, widely known as the "Rei do Baião" (King of Baião), a legendary Brazilian musician, is perhaps who you're referring to as Zé Gonzaga. Born on December 13, 1912, in Exu, Pernambuco, he was instrumental in popularizing the baião and forró, rhythms native to the Northeast region of Brazil. His music sings the life, the customs, and the struggles of the rural northeastern Sertanejo people, often with an underlying spirit of resistance.

Throughout his prodigious career, Luiz Gonzaga released numerous albums that have become classics in the Brazilian music scene. His iconic status led to several compilations of his greatest hits, like "20 Grandes Sucessos" which typically feature some of his most celebrated songs. Despite the different titles you mention, it is quite common in Brazil for record companies to release collections of popular songs from different phases of an artist's career, and titles such as "1951" and "1972" possibly denote compilations that focus on Gonzaga’s hits from those respective years. His influence extends far beyond his death on August 2, 1989, and his legacy continues to shape and inspire Brazilian music and culture to this day.
