At that time, with some encouragement from
Grigoris Bithikotsis, whom he met at a gathering at his uncle's company at which he sang, Mitropanos visited EMI-Lambropoulos Bros. Ltd. (EMIAL S.A.) There, Takis Lampropoulos introduced him to
Giorgos Zampetas, with whom he would work alongside at "Ksimeromata". Mitropanos considered
Giorgos Zampetas to be a great teacher and a second father to himself. As he stated, "Zambetas is the only man in music who helped me without expecting anything. With all my other colleagues, I got something and I gave something in return." In 1966 Mitropanos met
Mikis Theodorakis and sang the Party songs "
Romiosini" and "
Axion Esti" in a series of concerts in
Greece and
Cyprus. In 1967, Mitropanos recorded his first 7" single "Thessaloniki". This followed the recording of "Chameni Paschalia", a song that was censored by the
Greek military junta and thus never released. In a course mapped out by folk art music, 1972 is a milestone. The composer Dimos Moutsis and the lyricist and poet Manos Eleftheriou released "Agios Fevrouarios" with Mitropanos and Petris Salpeas as the song's performers, marking a milestone in Greek music. In July 1999, Mitropanos and Moutsis met again on stage at the "Odeon" with
Dimitra Galani and the soprano Julia Souglakou for two nights at the Athens Festival. The concerts were recorded live and released in a double CD two months later. George Katsaros's "The Road to Kythera" and
Giorgos Hatzinasios's "Ta Sinaxaria" follow suit, projects of high quality with a high profile in Greek society. In a long career in the
Greek music industry, Dimitris Mitropanos collaborated with leading artists of the
Laïko and
Éntekhno music.
