Notio Toxo is a group, consisting of four remarkable musicians who have blazed trails and marked new routes in folk music performing. The repertoire “Notio Toxo” is focusing on, covers a long period of consistently existing tradition, from the Middle Ages (rooting in antiquity) to current times, moving from rural, ritual and dance tunes to urban melodies of the Aegean Arc. All that is expressed through arrangements in a delicate and harmonic balance between the old and the contemporary.
The South Arc (Notio Toxo), Hellenic Arc or Aegean Arc is an arcuate tectonic feature of the
eastern Mediterranean Sea. It consists of an oceanic trench, the Hellenic Trench, on its outer side; two arcs - a non-volcanic outer arc and an inner volcanic arc, the South Aegean Volcanic Arc; and a marginal sea on its inner side.
Besides, the Aegean Arc is a land with common, linguistical and musical features and idioms, which form an area in the shape of an arc, starting from the west coasts of Anatolia, from the Erythraea peninsula and passing through the South Aegean islands to Rhodes, Cyprus, Crete, Cyclades islands, South Peloponnese, finally ending to South Italy.
