In 2003 she recorded a new album "Tragoudi Alliotiko" with songs by Mikis Theodorakis accompanied by the Kamerata Orchestra under Theodorakis's supervision. The album became a success in Germany, central Europe and in Greece. TV stations and tabloid newspaper reviewers celebrated her comeback while other publications and reviewers questioned the rationale behind Leandros' performance of songs from a political composer like Theodorakis. Around this time she appeared in many TV shows on German and Greek television including galas with José Carreras. The album made it to the 100 best selling records of 2003, and Theodorakis wrote that he considered her "among the two or three most important interpreters of work".
