MONTAGE is a film record of the Montaje/Lachenmann recital presented by the Proa Foundation on November 8, 2013 in collaboration with the Contemporary Music Series. The recital project revolved around three Pieces for three soloists by Helmut Lachenmann, a nucleus that manifests itself as an index of radicalism from which a story of the direction that guides the career of its author can be undertaken. The program concluded with the simultaneous performance of those three Pieces, a version that appears in the Lachenmanian catalog under the name of Montage and for which there is no score or record. What is heard at the conclusion of this documentary could be the only record, so far, of that ghost version that the composer advises not to try.

A group of actors and the director of the play set out through the streets of Buenos Aires in search of people who have never been to the theater. This is an open-ended work in terms of time, blending formats that range from stage performance to audiovisual media, with new episodes added each year. The characters, situations, and settings will be created based on the stories collected from the audience. At the same time, the relationships between the characters and the storyline will evolve over time, intertwining aspects of the real lives of the actors with the impact generated by their efforts to connect with the audience.
