Born in Malmö, he began rhyming at the age of 14 and had a brief stint as one half of the rap duo Stockholm Boogie. In 2013, Niello launched his solo career with the singles "Svett" and "Legenden," the latter of which reached Number 3 on the Swedish Singles Chart and received double-platinum certification. He followed up in 2014 with the singles "Arlanda" and "Ikaros," and then released his debut EP Vinden in 2015. Dahlia, his first studio album, appeared in 2019. A few years later, Niello and singer Lisa Ajax participated in the 2022 Melodifestivalen with the song "Tror du att jag bryr mig."
