Marriott was born in Switzerland but grew up in England. After uploading videos of his instrumental acoustic music, he attracted attention after diversifying into caustic YouTube commentary videos and Twitch livestreams. A debut single, "Slow Down", was released in May 2020, followed by the extended plays (EPs) No Left Brain and Bitter Tongues and his debut album Are We There Yet? in 2023. Marriott cites Foals and the Strokes as major influences and his music is generally described as indie rock.
