Swedish composer Karl-Birger Blomdahl’s image-sound composition Altisonans is an experimental film addressing the relationship between Earth and space. The word ‘Altisonans’ can be translated as ‘that which resounds from space.’ The film was initially made for Swedish television, where it premiered on 25 September 1966, and was the first time the composer transposed a sonic idea into visual material.
Directed by Karl-Birger Blomdahl
