Gilberto added, “Astrud was the true girl who took bossa nova from Ipanema to the world.
A cause of death has not been disclosed.
Astrud who had no professional recording experience happened to be in the room.
“Producer Creed Taylor said he wanted to get the song done right away and looked around the room.
Astrud volunteered, saying she could sing in English.
Creed said, ‘Great.’
Astrud wasn’t a professional singer, but she was the only victim sitting there that night.”
The original version of the song, intended as a demo, was a duet with her husband.
The track became a global hit and boosted the profile of bossa nova music internationally.
Astrud and Joao divorced in 1964.
“The Girl From Ipanema” was her only major hit, selling more than 2 million copies.
