Sao Paulo (AFP) - Brazilian music legend Gilberto Gil has been hospitalized for nearly two weeks with high blood pressure, doctors said, raising fears for the long-term health of the 73 year old.

Gil has been at a hospital in Sao Paulo since February 25 but it was giving away few other details other than to say he was under observation and having treatment.

Gil and Caetano Veloso shook the foundations of Brazilian music in the 1960s with Bossa Nova, a fusion of samba and jazz.

Gil, who once served as Brazil's culture minister, is one of the most respected musicians in the country, while also making a name for himself on the international stage.

The duo is scheduled to return to the stage in April with performances in Chile, Peru, the United States and Europe.
