This song is on one of Jorge Bens best records: O Bidu (Silencio No Brooklin) from 1967. This Brooklin is a district in the city of São Paulo, not New Yorks neighbourhood. In this period of his career Jorge Ben had moved from Rio de Janeiro to São Paulo. He was the first to use the electric guitar in samba. His previous records were all recorded with a acoustic guitar and had a more classical Bossa Nova and Samba sound. "Si manda" is a great up-tempo Samba Rock track with a powerful beat and electric rhythm guitar. This record and this song in particluar must have had a big influence on the Tropicalia movement and a band like Os Mutantes.
