Mexican music director and producer Lynn Fainchtein, known for her work as music supervisor on films such as Alejandro González Iñárritu’s Amores Perros and Alfonso Cuarón’s Roma, died on Friday (March 1) at the age of 61 in Madrid, Spain, where she lived, informed the record label Casete, which she co-founded.

A cause of death has not been disclosed; a spokesperson for Casete told Billboard Español that he had no information at this time. An outpouring of messages of condolences from musicians, cultural institutions, filmmakers, journalists, actors and personalities of the music and film industry in Mexico flooded social networks during the early hours of Friday, when news of her passing broke.

“Rest in peace Lynn Fainchtein, a beacon of light and music. May the best soundtrack always accompany you,” said Alejandra Frausto, Mexico’s Secretary of Culture, on her X account.

“‘Que Viva Mexico’ forever with your musical supervision, dear Lynn Fainchtein. In ‘Roma,’ ‘Babel,’ with ‘Abel,’ or with ‘Precious,’ ‘Los adioses’ (or goodbyes) are always sad,” wrote the Filmoteca de la UNAM, using titles of films in which the artist worked.

Fainchtein studied psychology at the Universidad Nacional Autónoma de México (UNAM), but for more than three decades, she served as an innovative broadcaster, film, radio and television producer.

In her early days, she worked as an announcer for the local Mexico City station Rock 101, where she met Mexican filmmaker Iñárritu, who was then working in advertising and voice-overs. Eventually, she became one of his closest collaborators in his award-winning film career.

With Iñárritu, she worked as music supervisor on all of his films, including the Oscar-nominated (and/or Oscar-winning) Bardo, The Revenant, Birdman, Biutiful, Babel, 21 Grams and Amores Perros.

“Alejandro always starts working on the music when he is almost finished with the script. For him, music is as important as production, art, wardrobe, makeup. He is a director who works on music a long time before and takes it as a very important part of his projects,” said Fainchtein in an interview with Billboard Español in December 2022.

In 2018, she served as music supervisor for Mexican filmmaker Alfonso Cuarón’s Roma, winner of the Golden Lion at the 75th Venice International Film Festival and Academy Awards for best director, best foreign language film and best cinematography.

In 2022, Cuarón invited Lynn to oversee and create the music for his first television series for Apple TV+, Augustus, which would premiere this year, starring Cate Blanchett, Kevin Kline and Sacha Baron Cohen, according to her official website.

She was head of programming and news producer for MTV LATAM until 2000. In 2012 she co-founded the independent record label Casete with musician and producer Camilo Lara, Héctor Reyes Guevara and Paco Arraigada.

As music supervisor and producer, she participated in numerous films and shows for Netflix, HBO, Amazon, Apple, Fox and Star+, among many other studios. She also collaborated regularly with La Corriente del Golfo, the production company founded by Gael García Bernal and Diego Luna, where she supervised the music for Abel, Déficit, J.C. Chávez and Mr. Pig.

Among her other major projects are David France’s Oscar-nominated documentary The Death and Life of Marsha P. Johnson, Patricia Riggen’s The 33, Luis Estrada’s ¡Qué Viva México, La Dictadura Perfecta and El infierno, as well as Jonás Cuarón’s most recent film, Chupa, released on Netflix in 2023.

Last year, Fainchtein supervised the music for Perdidos en la Noche, by fellow award-winning Mexican filmmaker Amat Escalante, which premiered at the Cannes Film Festival.
