In the early 1990s, a friend, the composer Stanley Silverman, had just come into possession of some musical scores written by great Brazilian musicians for the Walt Disney cartoon, "Saludos Amigos". He encouraged Robison to play one of these pieces as an encore at one of her 92nd Street Y concerts, a dance for flute and pandeiro, a large tambourine traditional in Brazil. Silverman invited the percussionist Cyro Baptista to join her. The flutist Irna Priore, who was at the concert, told her that in Brazil there was a huge repertory for flute in the choro, a tradition of popular song originating in 19th century Rio de Janeiro. Cyro Baptista's wife provided recordings and tapes of music that was largely unknown in the US. Robison began to work on it with Baptista and other Brazilian musicians, who toured with her and eventually they produced a recording, Brasileirinho. In the end the group became a trio: Cyro Baptista, Romero Lubambo and Ms. Robison. As she has said, "The fusion between the three of us, with Romero's elegant Bossa nova style and Cyro's mad world music percussion genius, created a whole new, very exciting sound. I called it 'Mistura Nova'!" The trio played together for over ten years.
