Starting his professional career in 1935 as a crooner in a Carioca gafieira, four years later he joined the group Namorados ao Luar, in which he enjoyed some success. With Marília Batista and her brother Henrique Batista, Gerardi formed the group Os Três Marrecos in 1941. In the same year, he recorded Não Faça Vontade a Ela (Nelson Cavaquinho). In 1944, when he was already the crooner for Simon Bountman's orchestra, Gerardi was hired by Rádio Transmissora. His first hit was the samba-canção Pergunte a Ela (Geraldo Pereira/Fernando Martins, 1948), but his biggest one was from 1950, the samba Antonico (Ismael Silva). After a stint at the Rádio Tupi, he went to Rádio Nacional in 1953, where he worked until his retirement. ~ Alvaro Neder, Rovi
