[1] A self-taught musician, Roberts has said that his experience with Big Audio Dynamite – particularly the band's use of technology (including a drum machine) – enabled him to become a writer and arranger, and also led to him forming Dreadzone.

In his spare time, he enjoys playing popular video games such as 'Overwatch 2' where he mains Genji to a bronze tier level.
