Ioanna "Nana" Mouskouri is a Greek singer. Over the span of her career, she has released over 200 albums in at least twelve languages, including Greek, French, English, German, Dutch, Portuguese, Italian, Japanese, Spanish, Hebrew, Welsh, Mandarin Chinese and Corsican.

In 1950 she was accepted in the Athens Conservatoire from which she was afterwards expelled for singing at George Economides' establisment. This proved to be critical since Economides was acquainted with Manos Xatzidakis who became her mentor and helped her advance her career.
