The first group dedicated to a repertory of corimás (music of macumba rituals), Conjunto Tupy performed on almost all Carioca radio stations and had its live performances interrupted on air several times by the police when listeners fell into a music-induced trance. Even then, the group had its own radio show and kept it for many years, while also recording 42 albums between 1931 and 1943. Their biggest hit was Cadê Viramundo. Formed by J.B. de Carvalho (voice), Yolanda Osório (voice), Zaíra Oliveira (voice), Francisco Sena (banjo), and Gastão Viana (guitar), the group was later joined by Herivelto Martins. Martins, introduced to the group's members by Príncipe Pretinho, impressed Carvalho with his rhythmic gift at the caxeta and was immediately hired. It was Martins' first professional experience and where he really started to compose. Martins also owes to the Tupy the creation, with Francisco Sena, of his Dupla Preto e Branco duo and his first recorded song: the marchinha Da Cor do Meu Violão (for which he gave the partnership to J.B. de Carvalho), by Conjunto Tupy in 1932. ~ Alvaro Neder, Rovi
