Daniel Virgil Maisonneuve (Sub Urban) was born on October 22, 1999, in Nyack, New York to a French Canadian father and a Taiwanese mother. While raised in the suburbs of Ridgewood, New Jersey, he began producing music at the age of 15. He was trained in classical piano at the age of 6, but quit after claiming that he was "sick of playing other people's compositions". In the fall of 2016, Maisonneuve dropped out of high school to pursue his musical career, "isolating" himself to work on various demos and songs. The most popular song of his to come out of this period of self-isolation was "Cradles", which skyrocketed in popularity after being shared heavily on video-sharing application TikTok.

In 2014 and 2018, Maisonneuve frequently collaborated with British producer DNMO on tracks such as "Sick of You" and "Broken". Maisonneuve states that "most of his inspiration has derived from artists such as K. Flay, EDEN, Aries, verzache, Joji, Cage the Elephant and NoMBe".

On March 13, 2020, Maissoneuve released his first EP, titled Thrill Seeker, where he has the participation of the South Korean hip-hop artist, REI AMI, with the song "Freak", accompanied by video and official audio.
