Thomas Headon was born in London. At age 5 his family moved to Melbourne, Australia, where he grew up.
As a young teenager he started posting cover versions of his favourite songs on Youtube, which helped him to start building an international fanbase. Influenced by the likes of The 1975, Coldplay, Tyler The Creator, Harry Styles and Rex Orange County, Thomas also started writing and producing original songs.
In 2019 he moved back to London to pursue his career in music and released his self-written and self-produced debut single Grace in September 2019, followed by Clean Me Up. Both songs became part of his debut EP The Greatest Hits, which was released in March 2020 and gained over 13 million streams. In June 2020 Thomas released Loving You, the first single of his second EP.
