Merton first drew major attention in 2015 as a songwriter and singer on Fahrenhaidt’s album The Book of Nature. On 14 November 2016 while in Hamburg she won the annual award for the promotion of talented newcomers in the category Acoustic Pop.
After moving to Berlin, Alice and her manager Paul Grauwinkel founded the record label Paper Plane Records International, and released the song “No Roots” at the end of 2016. The song’s lyrics were inspired by her feeling of “There’s no one place where my home is.”On both Hype Machine and Spotify’s Global Viral 50 charts the song reached number one, and was soon included on the “Hit Play” lists of several radio stations. The song was also featured on episode 5×09 of the NBC TV series, The Blacklist.
On the basis of this success, Merton officially released her first EP, No Roots, on 3 February 2017. No Roots reached number two on the German charts, and number one on the French charts. Vodafone Germany even included the song in one of its commercials. Alice signed with Mom + Pop Music in August 2017 for marketing within the United States and on 2 August 2017 she released her second single Hit the Ground Running with her new record label.
She performed at the Life Ball in Vienna on 10 June 2017, and ended the year touring throughout Germany, appearing as opening act for Bosse and Philipp Poisel, among others. In late 2017 she won the 2018 European Border Breakers Award
On 7 September 2018, Merton released “Why So Serious”, the lead single from her upcoming debut album, Mint. She is set to release the second single in November.
