As if directing a science-fiction film, Johana Ožvold dissects the story of electronic music. From the pioneer sound engineers working behind the Iron Curtain, through the French avant-garde composers, up to the post-modern creators of digital sonic artefacts, the first-time filmmaker summons an abstract landscape that is haunting and yet achingly beautiful. A voice appears from old television screens forgotten in the maze of some futuristic archive where past and future seem to coexist in a complex and multi-layered way.
Unfortunately the movie The Sound Is Innocent is not yet available on HBO Max.
