A specific form of éntekhno was the so-called "political song"; songs with political message, of the Left, which arose during the military junta and became very popular after its fall in the late '70s. Manos Loizos, guitarist Panos Tzavellas, Maria Dimitriadi and Maria Farantouri were some representatives. Thanos Mikroutsikos released an album featuring Greek partisan songs of the Greek resistance, with his own orchestration. A form of éntekhno which is even closer to western classical music was introduced during the late 1970s by Mikroutsikos.
