Astrud Gilberto, the Brazilian singer, songwriter and entertainer whose off-hand, English-language cameo on “The Girl from Ipanema” made her a worldwide voice of bossa nova, has died at age 83. “The Girl from Ipanema,” the wistful ballad written by Antônio Carlos Jobim and Vinícius de Moraes, was already a hit in South America. But “Getz/Gilberto” producer Creed Taylor and others thought they could expand the record’s appeal by including both Portuguese and English language vocalists. “Getz/Gilberto” sold more than 2 million copies and “The Girl from Ipanema" became an all-time standard.
