Maria Farantouri or Farandouri is a Greek singer and also a political and cultural activist. She has collaborated with Greek composers such as Mikis Theodorakis, who wrote the score for Pablo Neruda's Canto General, which Farantouri performed worldwide.

The "Mauthausen Trilogy", also known as "The Ballad of Mauthausen" and the "Mauthausen Cantata", is a cycle of four arias with lyrics based on poems written by Greek poet Iakovos Kambanellis, a Mauthausen concentration camp survivor, and music written by Greek composer Mikis Theodorakis. It has been described as the "most beautiful musical work ever written about the Holocaust", and as "an exquisite, haunting and passionate melody that moves Kambanellis' affecting words to an even higher level".
