Ataraxia is an Italian neoclassical Goth opera band who combine modern technology with archaic instrumentation over various media. They describe their music as a cross "between sacred and profane, ethereal and neo-classical, contemporary and early music". They make researches into the European legends crossing the Greek and Latin myths. Their lyrics are written in many ancient and contemporary languages. Many of their performances take place in locations the band believes to possess specific spiritual qualities. Since the beginning of the group in the late 1980s, they have released more than 20 original LPs.(from wikipedia)
