LC Concept was a 35 mm film projection sound format, developed in France and released in 1991.
It used 5.25" 300 megabyte capacity re-writable magneto-optical disks to hold 4 or 5.1 channels of MUSICAM compressed audio.
A large litigation against Universal Studios, Steven Spielberg and DTS frightened the investors.
The system was tested with a re-release of the Cyrano de Bergerac, and the first commercial release was Until the End of the World.
