Throughout his career, Peterson has promoted the new frontiers of jazz, hip-hop, and electronic music. Starting by installing illicit transmitters and hosting shows for pirate radio station Radio Invicta, he later joined the newly-founded Jazz FM and, after that, joined the pirate-turned-legal station Kiss FM. In 1998, he was hired by BBC Radio 1, where he hosted a weekly show until his move to his current slot on BBC Radio 6 Music.
Since 2005, he has hosted the annual Worldwide Awards in London and Worldwide Festival in Sète, France, and in 2019, he launched the new We Out Here festival in the UK. In early 2021, Gilles released the Str4ta album (with Bluey from Incognito) and his first full length book ‘Lockdown FM – Broadcasting In A Pandemic’.
