Suzanne Danco was praised for her wide musical culture and refinement both on stage and in recital. She was trained entirely in her native Brussels at the Conservatory. Danco was much admired for her Mozartian roles and for Melisande in Debussy's Pelleas et Melisande (she can be heard on the celebrated Decca recording with Ernest Ansermet conducting).

Danco was sometimes criticised for a 'coolness' in her singing. Hers was more of an 'instrumental' sounding voice than a full-blooded Italianate one. It was especially suited to the improved medium of recording after WWII and her recordings for Decca in the 1940's and 50's are justly prized.

In her later years, Danco was much in demand as a teacher. She died in Fiesole, just above Florence, Italy in the late summer of 2000.
