[5] Born and raised in Nantes, he started learning piano at the age of four and found inspiration in one of London's clubs while studying.

In reaction to his mother's death, Redcar released an EP in 2020 La vita nuova, with some critics calling it his strongest work up to that point.

[14] His parents recommended to him writers such as Sarah Waters and Judith Butler, whose works served both as inspiration and reference in Redcar‘s youth.

[17] He made a trip to London and was inspired by the work of local drag queen musicians, including Russella, at the Soho nightclub Madame Jojo's.

[19] As soon as he returned to France, he left the ENSL grande école in the middle of the second year to devote himself fully to the musical project now called "Christine and the Queens".

[14] For the American market, the single "Tilted", English version of "Cripple"/"Christine", was released on 3 March 2015 under the Neon Gold Records label.

Exclusively for this market, Saint Claude EP was released on 14 April, including five songs from Chaleur humaine in English versions.

[26] On 11 November, Christine was warmly received in his first performance in large venue, the Webster Hall, New York; the next day, he appeared on The Daily Show.

[30] At the end of the year, he was back home, and, on 10 December, Madonna invited Christine to dance with her on stage during her concert at the Bercy Arena, Paris.

[36][37] In September, he put together a cover version of Beyoncé's "Sorry" in the BBC Live Lounge; for arrangement and rendition he was included in the "6 Best New Songs of the Week" list by Vulture.

[1] For his second studio album, Redcar had early sessions with both Mark Ronson and Damon Albarn, but eventually decided to work alone, with Cole M.G.N.

[43] AllMusic editors summarised: "the singer/songwriter's triumphant second album borrows from '80s R&B and questions gender roles, engaging minds, hearts, and bodies along the way.

"[44] Robert Steiner of The Boston Globe called the album "a refreshing, empowering record" and complimented its "stellar production and contagiously danceable jams", as well as Redcar "engrossing lyricism".

Although he felt that the album "loses steam" in its second half, Steiner named "The Walker" as a highlight for its "poignant" portrayal of a victim of domestic violence.

[49] On 17 July, Charli XCX released the single "Gone" alongside the music video, a joint effort with Redcar, which they debuted earlier together at the end of May during the Primavera Sound festival.

[50] The track was shortlisted by BBC Radio 1 DJ Annie Mac for the Hottest Record of the Year, voted for by the public, and finished in third position.

[54] Redcar simultaneously released a conceptual short film directed by his longtime collaborator Colin Solal Cardo.

[55] NME's El Hunt gave a rave review, summarizing; "conceptually, 'La Vita Nuova' is an astonishing feat – but even better than that, it also oozes an intensity of feeling that punches right in the gut.

[57] "People, I've Been Sad" was recognized by Time as song of the year and also placed in the top-three of year-end critics' lists by NPR, Pitchfork, and The Guardian.

[58] The short film was included in Pitchfork's list of "The 20 Best Music Videos of 2020"; Ryan Dombal wrote: "this is art-pop cinema that's both steeped in history and gloriously unafraid to blaze its own way.

[62] In June, Redcar performed "I Disappear In Your Arms", recorded in an empty music venue, on The Tonight Show Starring Jimmy Fallon, and then "La vita nuova", filmed inside the empty Grand Palais, on Global Citizen's Global Goal: Unite for Our Future virtual benefit concert.

[63][61] On 2 July 2020, he debuted "Eyes of a Child", a track created for the second season of the Amazon Prime Video series Hanna; the single had been released earlier to streaming platforms on 25 February.

[65] On 4 November 2021, Charli XCX released "New Shapes" featuring Redcar and Caroline Polachek as the second single from her studio album Crash (2022).

[70] On 8 March 2023, Redcar released the song "To Be Honest" as the lead single from his fourth studio album Paranoia, Angels, True Love.

[71][72] Returning to the name Christine and the Queens for the album, he described it as "the second part of an operatic gesture that also encompassed 2022's Redcar les adorables étoiles".

[73] On 30 June 2023, Redcar was a guest celebrity judge in Episode 1 of Drag Race France Season 2 titled A Lé-Gen-Daire Return broadcast on France.tv Slash.

[74] In 2024, Amazon licensed the song "Full of Life" from Paranoia, Angels, True Love for a 60-second ad called "Concrete Jungle".

[75] On 20 February, MGMT released the single "Dancing in Babylon" featuring Christine and the Queens ahead of their fifth studio album Loss of Life.

[4] In July 2024, Redcar, expressing frustration with both his record label and not being invited to perform during the 2024 Summer Olympics opening ceremony, leaked his fifth studio album Hopecore by sharing a WeTransfer link on his official social media accounts.

[85] In a November 2013 interview with Brain Magazine [fr], he cited artists such as Christophe, David Bowie (especially his Ziggy Stardust character),[86] Kanye West, Kendrick Lamar, Philip Glass, T. Rex as well as the Soul Train soundtracks as his musical influences.
