[2] Richardson's career in the music industry started off in the mid 1990s, working as a producer in his local area in Wales.

[3] By the late 1990s he was working as an engineer at Front Line Studios in Caerphilly, which is where he first met the other members of Lostprophets.

In October 2013, ten months after lead singer Ian Watkins was arrested and charged with multiple sexual offences, Richardson and the remaining members of the band announced that they could "no longer make or perform music as Lostprophets".

During an appearance on the Sappenin' Podcast with Sean Smith in December 2019, Richardson revealed the reason why they formed a new band.

"[6] During the same interview, Richardson revealed that he had engaged in a violent altercation with Watkins in 2012, as the latter's drug use put much strain on his relationship with the remaining band members prior to his conviction.
