urban music scene, he set up his Madhatter Soul Sound System in the 80s. Nelson started his broadcasting career on the fledgling
London's
Kiss FM, originally a
pirate radio station. Nelson helped the station become legal and gain a licence in 1990. Nelson was both a daytime DJ and director. In 1996, Nelson moved to
BBC Radio 1 to present the first ever national R 'n' B show,
The Rhythm Nation and moving to Saturday and Sundays 47pm, showcasing the best in new and old R&B music, with DJ Ace taking over his slot. He had held this slot since 2011 after leaving the 1Xtra breakfast show which he presented with
Gemma Cairney and previously
Zena McNally. In 2010 he was awarded with the special gold lifetime achievement award for his services to broadcasting, at the Sony Radio Academy Awards. On 21 March 2017 he was a presenter for
Sara Cox's
Red Nose Day danceathon from 2am to 5am. In August 2017, April 2018, and again in August 2018, Trevor sat in for
Ken Bruce on his Radio 2 show. On 29 October 2018 it was announced
Sara Cox would take over drivetime on Radio 2. As a result, from January 2019 ''Trevor Nelson's Rhythm Nation'' would move to Monday-Thursday 22:00–0:00. In the summer of 2022 Nelson hosted
Exodus: Bob Marley Reimagined; the
BBC concert took place to mark the 60th anniversary of
