After Jordan’s performances of two Billie Holiday songs, “Gloomy Sunday” and “I’m a Fool to Want You”, on Norway’s Got Talent, as well as “Fly Me to the Moon” on a TV talk show, all went viral online in March 2014, she was featured in Time, Daily Mirror, People, and other news outlets around the world. She continued in the competition singing Nancy Sinatra’s version of “Bang Bang (My Baby Shot Me Down)” live in the semifinals, and won with her performance of the George Gershwin’s “Summertime”, in the style of Ella Fitzgerald and Louis Armstrong’s 1958 recording of the song.

In September 2014, she performed “Fly Me to the Moon” on the US television show The View, bringing her wider fame in the United States. She also performed on several TV 2 programs in Norway over the next few years, including multiple appearances on Allsang på Grensen (Singalong at the Border, referring to the border fortress of Fredriksten where outdoor concerts are held) and on TV4 in Sweden.

In December 2014, she realized a personal ambition by performing for Peace Prize recipients Malala Yousafzai and Kailash Satyarthi at the Nobel Peace Prize Concert.

Jordan’s recording debut, the three-song maxi-single My Christmas, was released in December 2014. To support the release, Jordan performed the songs on multiple TV shows, including an appearance on Christmas day.

In 2015, Jordan began recording music that would eventually be collected on the six-song Angelina Jordan – The EP, released on 27 November 2017. Many of the tracks were posted to her official YouTube channel well in advance of the EP release, in the form of music videos and lyric videos. These included her covers of Screamin’ Jay Hawkins’ “I Put a Spell on You”, the music video for which was directed by Per Heimly, and Amy Winehouse’s “Back to Black”, in which Jordan sang her own original lyrics. These two music videos became the most popular videos on her official YouTube channel, surpassing 5 million views each by 2020. In 2017, she created a second YouTube channel specifically to present performances of cover songs,

In November 2015, Jordan published the book Mellom to hjerter (Between Two Hearts), illustrated by her grandmother, Iranian artist Mery Zamani. The book tells the story of her meeting a poor motherless girl in Asia who has no shoes. After a long conversation in which they discuss their dreams in life, she gives the girl her shoes and the girl promises to pray for Jordan to fulfill her dream to become a successful singer. According to Jordan the book is based on a real incident which she cites as the reason for always performing barefoot.

In April 2016, Jordan performed “Fly Me to the Moon” on the first season of the noncompetitive children’s talent show Little Big Shots. A year later she performed “What a Difference a Day Makes” on the UK version of the show. She also performed “I Put a Spell on You” on the German edition of the show, Little Big Stars, in 2017.

In December 2016, she performed on Alan Walker is Heading Home, a live concert broadcast from Bergen, Norway, where she sang Walker’s songs “Sing Me to Sleep” and “Faded”.

On 15 June 2018, a full album of recordings with Staff Band of the Norwegian Armed Forces (Forsvarets stabsmusikkorps), called It’s Magic, was released. The next day, Jordan and the band performed the full album live in a concert attended by Norway’s Prime Minister.

On 27 June 2018, Jordan performed “Fly Me to the Moon” for Quincy Jones in The O2 Arena in London, as part of his 85th birthday celebration, and also joined with other singers to perform “Man in the Mirror” to close the show.

In 2019, Jordan performed for former president Barack Obama and other public figures at the Brilliant Minds conference in Stockholm.

In October 2019, she competed in the second season of America’s Got Talent: The Champions, which was aired in January and February 2020. Her first appearance on the show, singing an original arrangement of Queen’s “Bohemian Rhapsody”, received a “golden buzzer” from judge Heidi Klum (meaning that Jordan would pass directly into the finals). As with her Norway’s Got Talent audition six years earlier, a video of Jordan’s performance began to go viral on YouTube, quickly reaching 10 million views. The performance also garnered praise from Queen’s official Twitter account. Shortly afterwards, the video was taken down and Jordan released a studio version of the same arrangement under her own copyright. Jordan’s second performance (in the finals), a similarly reworked “Goodbye Yellow Brick Road” based largely on a version by Sara Bareilles, was also well received, but she was not among the top 5 acts.

In August 2020, Jordan’s manager (her uncle, Michael Astar) announced that she had signed with Republic Records. Her first single on the label, “Million Miles”, was released on 6 November 2020, on all major digital platforms. An official lyric video was posted to her official YouTube channel the same day. The track was produced by the Norwegian duo Stargate, who also co-wrote the song with Jordan.

As of 2020, she is living and going to school in Los Angeles.
