Organist Juan de la Rubia and visual artist Eugèna Balcells have come together to conceive this concert in which several visual scores created by Balcells in the 1980s will be improvised upon on the organ.

This interdisciplinary dialogue will also include a reference to the father of organ improvisation, Johann Sebastian Bach, from whom Juan de la Rubia will perform the Passacaglia and fugue BWV 582 and for which Eugènia Balcells will put in dialogue four of her recent works, as well as a new piece created specifically for this concert. The concert will finish with improvisation on the organ over the projection of Frecuencias.
