The Lausanne Underground Film & Music Festival (LUFF) is an annual event held in Lausanne, Switzerland, dedicated to showcasing and promoting innovative, subversive, and independent films and music that do not typically benefit from wide distribution. Organized by a non-profit organization, the festival aims to fuse music and cinema, presenting experimental films that challenge conventional viewing habits alongside live music performances by underground artists. LUFF features film competitions for both feature and short films, as well as non-competition sections for documentaries and various retrospective programs.
