Annna

In late 2019, Pērkone submitted the song "Polyester" to Supernova, the Latvian preselection for the Eurovision Song Contest 2020 to be held in Rotterdam, the Netherlands. In January 2020, it was announced that she and 25 other acts had been shortlisted from the 126 entries received by the Latvian broadcaster LTV. She survived a second elimination round and proceeded to the final on 8 February 2020, where she finished third out of nine finalists.

At the age of 17, Pērkone moved to the Netherlands to study European studies at Maastricht University, but ended her studies early to focus on her musical career. With the Amsterdam-based electropop band Madara, she recorded an EP while on tour in Colombia. When she returned, Pērkone decided to pursue a solo career as Annna. In 2019, she released three singles: "Swim", "The One That Got Away" and "Stardom/Hater". In August 2019, Pērkone was the opening act for the American singer LP at a concert in Sigulda. She subsequently gained popularity in Latvia, and her single "The One That Got Away" reached position 1 in the top 50 most played songs on radio station Star FM. With the track "Stardom/Hater", she won the 24th edition of the competition Demolition at the 2019 Amsterdam Dance Event.
