She followed this in 2014 with the EP Strange Weather and subsequently wrote the music for a stage production of the opera The Sandman, directed by Robert Wilson.

This eclectic array ranged from Captain Beefheart to The Rolling Stones to Maria Callas, combined with classical music: "I was so taken by the sound.

[7] She also came to be much influenced by 20th century composers Messiaen, Ravel, and Debussy, attracted "to the impressionistic element of the music," and would try to recreate this feeling on the guitar.

[15] Following her completion of university, Calvi returned to London and worked as a guitar instructor, giving private lessons,[16] though she reflected: "I was rubbish because I had taught myself so I couldn't explain how to play.

"[7] In an effort to find her own voice, Calvi has spoken of how she would lock herself in a room for long periods of time, singing along to records by Edith Piaf and Nina Simone.

[7] In the autumn of 2009 Calvi recorded a series of filmed Attic Sessions that were uploaded onto YouTube, including a cover of Leonard Cohen's "Joan of Arc", Elvis Presley's "Surrender", TV on the Radio's "Wolf Like Me" and David Bowie's "Sound & Vision".

[22] In 2010 Calvi supported American rock band Interpol on their United Kingdom tour, as well as label-mates the Arctic Monkeys at the Shepherd's Bush Empire.

[24] On 11 October 2010, Calvi released her debut solo single "Jezebel", a 1951 song originally written by Wayne Shanklin and made famous by Frankie Laine and French chanteuse Edith Piaf.

[25] Live versions of both "Jezebel" and "Moulinette" were filmed at The Luminaire venue in London by Emma Nathan, who also created the vinyl artwork.

It's a fearless rejection of current pop trends, fashioning a benchmark of intensity and originality that the rest of this year's albums will struggle to match.

It's always important to me that the music tells the story as much as the lyrics, so I was very focused on creating rich textures and a lot of atmosphere for the songs to exist in.

Reviewing this special performance, Gigwise said that "up close and personal, the microscope highlights the nuances and flourishes that make Calvi the rarest of talent".

The concert was a sold-out event which also saw guest appearances from Patrick Wolf and Charlie Fink from Noah and the Whale, and Dave Okumu producer and musician from the band Invisible.

[61] On 3 March 2015 Calvi confirmed via her Facebook page that she would be recording a track for the 2015 science fiction film, The Divergent Series: Insurgent.

The film's soundtrack was released on 17 March 2015 through Interscope Records and featured other artists including Woodkid, Lykke Li, M83, HAIM, Royal Blood, SOHN, Zella Day, and Imagine Dragons[62] Calvi was once again a judge at the 2015 Mercury Music Prize.

[64] In March 2016, Calvi was part of the Pieces of a Man: The Gil Scott-Heron Project, "a celebration of the life and legacy of the legendary American soul and jazz poet, musician, and author" in conjunction with Convergence Festival in London.

[65] Under the direction of The Invisible's Dave Okumu, an ensemble of guest vocalists and poets, including Andreya Triana, Kwabs and Jamie Woon performed reinterpretations of Scott-Heron's music.

[73] Hunter was received well by critics, earning a five star review in The Guardian, who deemed it "glorious and triumphant", and "a record that succeeds on any terms you try to force upon it,"[74] while Pitchfork Media rated it 7.8 out of 10 and praise Calvi's "remarkable evolution" which "pushes her artistry to another level".

Complicated narratives, quotable one-liners, and cunning plans that would put Baldrick to shame play out against a smorgasbord of ostentatious '20s glamour and opulence.

The gang are out of their depth in high society, trying to pass themselves off as upstanding members of the community, however, the inevitable pull of violence, power struggles, turf-wars and revenge are never far from their minds.

Often using high levels of reverb, the score is all woozy electric guitars, dissonant chords and distorted riffs – and full on rock and roll – heightening the sense of unease and conflict amongst the characters.

Key score moments include a beautiful melody juxtaposing a particularly violent (even for him) Arthur Shelby beatdown, and a tense assassination attempt where the guitar is strung out like the viewers' nerves."

[82] Calvi is set to feature on Jeff Goldblum's upcoming second album I Shouldn't Be Telling You This for a mash-up of Wes Montgomery's "Four on Six" and Marianne Faithfull's "Broken English".

[83] 2022 saw Anna Calvi score the long-awaited sixth and final season of Peaky Blinders alongside producer Nick Launay.

[3][87] She has stated she aspires to create orchestral soundscapes with the guitar,[33][88] and is noted for her particular style of playing which involves hitting the strings in a circular motion, rather than strumming up and down.

[89] The result has been described by Q as "the prodigious wash of sound that recall Ennio Morricone, Duane Eddy, even Jimi Hendrix in its fluidity.

[92] Calvi has cited Nina Simone, Maria Callas, the rock of Jimi Hendrix, The Smiths and the Rolling Stones, the blues of Captain Beefheart, the stage performances of David Bowie, Nick Cave, and Scott Walker as well as classical composers Messiaen, Ravel and Debussy as among her influences.

[95] Visually, Calvi nods to the world of flamenco in her stage outfits, opting for the high trousers and blouse of a male dancer rather than the traditional frilled dress.

[citation needed] The fashion designer Karl Lagerfeld said he was a fan of her music,[100] and photographed Calvi for the Maison Michel Fall Winter 2011 lookbook.

[103] On 20 February 2017, Calvi performed four of her own tracks (including two new songs) and a cover of Christine and the Queens 'iT' at the Burberry London Fashion Week show with strings and a choir from The Heritage Orchestra.
