Born in Auckland, New Zealand and now residing in New York City, Dion has played in various bands, most notably The D4, who released two albums on legendary New Zealand label Flying Nun Records and A Place To Bury Strangers, appearing and writing on their studio albums Worship (2012), Transfixiation (2015), and Pinned (2018) as well as numerous singles and EPs. He also played in the formidable Flowers Of Evil beside members of Crocodiles.
While taking a break from touring with A Place To Bury Strangers, Lunadon recorded a self-titled solo album encompassing all that he loves about rock ’n' roll. Previewed by the single "Com/Broke," Lunadon's LP arrived in 2017 on Agitated Records.
Just as the pandemic hit early 2020, Lunadon decided to leave A Place To Bury Strangers and focus on his own music. In June 2020, he released the song “When Will I Hold You Again”, a duet with Kate Clover, and September 2020 saw the release of the Schreien EP.
In 2021 he put a band together to give his songs life and in 2022 Henry Rollins got him in touch with In The Red Records who released his sophomore album, Beyond Everything.
November 14, 2023 saw In The Red releasing his third album, Systems Edge.
