The surrealistic poetry of Guillaume Apollinaire forms the background for the choral suite Calligrammes. The work was commissioned by the Swedish Broadcasting Union to be performed by The Swedish Radio Choir together with a dancer and a vocal soloist – all of which performed on custom-built digital musical instruments. These instruments have been developed by Åsa and Carl Unander-Scharin in collaboration with Ludvig Elblaus.  The innovative artefacts are created to allow for explorations of artistic interaction between physical movement, musical soundscapes and vocal performance.
