(Labyrinth Original Sound Track) is the world's largest Labyrinth art and electronic music festival.

The Labirinto della Masone, inaugurated in 2015 in Fontanellato (Parma), is a seven-hectare park composed of more than 200,000 bamboo plants, the fruit of the dreams and visions of Franco Maria Ricci, esteemed publisher, graphic artist and refined collector.

In line with the artistic vision of its founder, Lost organizes special events inside the Labyrinth related to contemporary languages, interweaving art, experience and experimentation.

Conceived as an immersive event and promoted by the Franco Maria Ricci Art Foundation, Lost Music Festival celebrates contemporary expressions through a careful selection of Italian and international artists, bringing to life the mystical, esoteric and unknown aspects of this unique space. As the bamboo forest becomes a backdrop for human creativity, performances and installations come together creating a unique experience of sound, light and nature, blurring the boundaries between reality and the unknown.
