The famous Montreux Jazz Festival has been capturing the concerts that take place under its auspices in both audio and video recordings for many decades, so preserving them for future generations. The Montreux Jazz Heritage Lab (MJHL) is a specially constructed modular room. It has been created to give visitors wishing to consult the concert archives, which now exist in digital form, the opportunity of experiencing these recordings with total visual and acoustic authenticity. The curved projection screen has been inspired by the trompe-l’œil effect which the Baroque era used with such virtuosity. It gives the viewer the illusion of being physically present and in the thick of things. Acoustic considerations were an important factor in planning the geometry of the MJHL and in the choice of materials. With a view to allowing a wider audience as well to enjoy the concert experience, the side partition of the room is designed as a door and can be opened out completely.
