The Lausanne Underground Film and Music Festival (LUFF) is a film festival and music festival devoted to underground film and music. It is held each year in Lausanne, Switzerland. The festival is organized by a non-profit organization (APCI - Association pour la Promotion de la Culture Indépendante). The organization's goals are to promote independent artistic projects and creations and to make those projects accessible to a large public. The primary goal of the Lausanne Underground Film & Music Festival is to present films and music that largely exist outside the mainstream and profit driven production and distribution circuits. The cinematic section presents mainly films with an experimental character and/or films that challenge the spectator's viewing habits. Films are screened during the day and evening, followed by live music events featuring underground artists at night. Money prizes are awarded by the festival for the films selected in the international competition, in order to support the filmmakers in creating their art. The musical program of the festival proposes sonar experimentations of all kind.
