revival groups (and solo artists) appeared. The most notable of them include Opisthodromiki Kompania, Rembetiki Kompania, Babis Tsertos, Agathonas Iakovidis and others. Éntekhno Drawing on rebetiko's westernization by Tsitsanis and Chiotis, éntekhno (or éntechno) arose in the late 1950s. Éntekhno (lit. meaning 'art song') is orchestral music with elements from Greek folk rhythm and melody; its lyrical themes are often based on the work of famous Greek poets. As opposed to other forms of Greek urban folk music, éntekhno concerts would often take place outside a hall or a night club in the open air. Mikis Theodorakis and Manos Hadjidakis were the most popular early composers of éntekhno song cycles. They were both educated in Classical music and -among other reasons- the lacking of a wide public for this kind of music in Greece, drove them to the invention of Éntekhno, in which they transferred some values of Western art music, such as ballads tune. Theodorakis was the first composer to use the bouzouki in this genre of music, trying to include this organ into the mainstream culture. Other significant Greek songwriters included Stavros Kouyoumtzis, Manos Loïzos, and Dimos Moutsis. Significant lyricists of this genre are Nikos Gatsos, Manos Eleftheriou and poet Tasos Livaditis. By the 1960s, innovative albums helped éntekhno become close to mainstream, and also led to its appropriation by the film industry for use in soundtracks. 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.
