With encouragement from composer
Mohammed Abdel Wahab, Kaddo sought a musical career in
Cairo. Her first concert in the United States was in March 1955, with her brother and other Lebanese musicians, at Brooklyn's
Hotel Bossert. and Los Angeles that spring. In 1956 she sang at events in Miami and Jacksonville, Boston and Hartford, and across New York State, including a benefit concert in Syracuse. She made further recordings in the United States, on the Eastern Star and Zodephone labels, and later on her brother's Kaddo Records label. In her later years, Kaddo was considered "the grand dame of the Arab-American singers", especially in Detroit. "My voice is better now," she said in 1990. "When you're younger, you can hit higher notes. But I put a lot more feeling into singing now". ==Discography==
