In 2015, Lanzon auditioned for The X Factor (Australian TV series) season 7 as part of In Stereo (band). They made the final 12, and were mentored by Guy Sebastian, eventually placing seventh. The group were signed with Warner Music Australia and released three extended plays, two of which peaked inside the ARIA Chart top 20.[3] before breaking up in 2018. In 2023 Lanzon told NME he felt disillusioned during this time, "I was living a completely inauthentic self. I didn't really feel like there was any sort of substance there that felt true to who I was."[2]
