Although music played an important role in the British singer/songwriter's life, it wasn't until age 18 that the Kentish Town-born musician started to write. Her first single, "Closer," was penned in her spare time while Muller worked at a local bar. After a subsequent run of singles including the Simbarashe-produced "Underwater," she released her debut EP, After Hours, in February 2018. Self-described as a "soundtrack to feeling good," the five-track project established Muller's identity, employing a varied set of production styles with lyrics reflecting on relationships and self-empowerment. This was followed in December by second EP Frankly; pushing in different vocal directions, the release saw Muller focus more heavily on voice, toning down the production in favor of softer tones and a greater vocal range.
In early 2019, both EPs were compiled into Muller's debut mini-album, Chapter 1, which featured three new tracks, including the self-empowerment anthem "Leave It Out." A string of single releases closed out the year. After the candid "Anticlimax," Muller linked up with Ms. Banks and Caitlyn Scarlett for "Drama," as well as releasing the October single "Dick." She opened 2020 with the single "Therapist," debuted live on tour with pop outfit Little Mix. The EP no one else, not even you arrived later that year.
Muller had a breakthrough hit in 2021 with "Better Days," a collaboration with Neiked and Polo G that reached number 32 on the U.K. singles chart and the Top 30 in the U.S., Australia, and Norway, among a handful of other countries. This time teaming up with Marshmello and Trippie Redd, "American Psycho" followed in mid-2022, with the solo effort "I Just Came to Dance" appearing before the end of the year. ~ David Crone, Rovi
