Dartell Eugenio Mercera, better known by his stage name Knaller, was born in the Schilderswijk neighborhood of The Hague. The rapper never knew his father, and he lost his mother to cancer at a young age. As an artist, Knaller shares raw street emotions through his music.

Knaller began his career as an independent artist and released several standalone singles in 2017. After making a name for himself, he signed a contract with The Hague-based label Wilde Westen Records in the summer of 2018. Here, Knaller released his debut album ‘Zonder Vader Zonder Moeder’ in 2020, which generated over 30 million streams.

In 2021, Knaller left the Wilde Westen Records label and signed with SPOW Business, the label of rapper 3Robi. He released ten singles under this label, and in 2022, he independently released his second album, ‘Better Days.’

Currently, Knaller is focused on his upcoming third album.
