As a Singer, Sylvia Dedicated her Short Career to One Man, Antonio Carlos Jobim. Of the Little More Than a Hundred Songs that She Recorded During her Ten Years in the Studio, at Least Fifty were Composed by Jobim, Written Either Alone Or in Partnerships. He was Always the Most Recognized Composer of his Generation. His Admiration of her was Reciprocal Because Many of Those Songs, Hot off the Piano, were Given Directly to Her. Sylvia Provided the Definitive Versions of Many Jobim Songs, Setting the Standard for them to Be Sung by Others.
