Mouzanar studied under Armenian-Lebanese composer Boghos Gelalian. In the year 2000, he established his first label ‘Mooz Records’ through which he produced the majority of Beirut's underground music scene. Groups such as
Soap Kills and The New Government were among these productions. One of his first professional experiences in cinema took place in 2005 with
After Shave – a short film directed by Hany Tamba. The film won in France the
Cesar Award for Best Short Film in 2006. In 2007, and while signing with the French independent record company
Naïve Records, Mouzanar composed the score for
Caramel – a feature film directed by
Nadine Labaki whom he later married. That same year, Mouzanar recorded his first solo album (in French) entitled
Les Champs Arides. In 2009, he composed the music for the opening ceremony of the
2009 Jeux de la Francophonie, which was viewed by 60 million spectators all over the world. French choreographer
Daniel Charpentier directed the show. In 2010, while writing for different artists such as
Natacha Atlas, Mouzanar composed the music score for the film
Where Do We Go Now? directed by Nadine Labaki, for which he won the award for Best Music at the
2011 Stockholm International Film Festival. In 2014 he scored the soundtrack of the film
Rio, I Love You (Portuguese: Rio, Eu Te Amo) and co-wrote the segment directed by Nadine Labaki. In 2017 he produced, co-wrote the scenario and composed the music of
Nadine Labaki’s feature film
Capernaum (film). The film won the
Jury Prize in
Cannes Films Festival 2018, and was nominated at the
Cesar Awards,
The Golden Globes and the
Academy Awards (The Oscars) for Best Foreign Film. For this film Mouzanar got also nominated at the
British Academy Film Awards (BAFTA). In summer 2018, Mouzanar and his orchestra opened the prestigious
Baalbeck International Festival with the score of Capernaum in the temple of Bacchus. In 2019 Mouzanar won for the Soundtrack of Capernaum a Crystal Pine Award for Best Original Score at the International Sound & Film Music Festival (ISFMF) and was nominated for the Public Choice Award at the
World Soundtrack Awards. In 2020 Mouzanar was invited by the
Academy of Motion Picture Arts and Sciences (The Oscars) to be among its distinguished members in the music branch. That same year he co-directed with his wife
Nadine Labaki the episode 11 (Mayroun and the Unicorn) of the
Netflix series
Homemade. In 2022 Mouzanar scored the soundtrack of one of Netflix's great success of the year, the movie
Perfect Strangers. That same year, Mouzanar founded the festival De Vin Et De Musique in the region of Batroun. In 2025, Mouzanar conceived “18:08-When Gravity Was No More” as a large-scale immersive installation reflecting on the Beirut port explosion of 4 August 2020 and its aftermath. The work recreates a suspended moment in which everyday objects—furniture, architectural fragments, musical instruments, and personal belongings—appear frozen in mid-air, as if gravity had momentarily ceased to exist. Visitors walk through a three-dimensional tableau that evokes both the violence of the blast and the surreal stillness that followed it. An original sound composition by Mouzanar, titled The Pulse, accompanies the installation. The installation that was part of
We Design Beirut, draws directly from Mouzanar’s personal experience: his music studio and office were destroyed in the blast, and several suspended objects reference real items recovered from the site. The work functions both as a memorial and as an artistic testimony, blending documentary fragments with poetic abstraction. Among Mouzanar’s contemporary works is also “Le Monde va à la guerre et moi j’en reviens”, the first chapter of an animated feature film in preparation with
Nadine Labaki and Jorj Mhaya, which was presented as an installation at the
Biennale d'art contemporain de Lyon in 2022. In 2025 he also collaborated on the song “Toi l’enfant” on the album
Lamomali by French artist
–M– (
Matthieu Chedid), a project blending pop, African, and world music influences. Mouzanar is also an activist working on the preservation of Lebanon’s heritage by preventing the demolition of traditional houses and preserving green spaces. He is also the co-founder of the Capernaum Foundation which takes care of children with no access to education. == Discography ==
