On 23 October 2015, DJ Madd was a guest on Solid Steel. DJ Madd has been played on NTS over 20 times, featured on 17 episodes and was first played on 17 July 2013.

Hungarian-born producer DJ Madd is widely recognised on the dubstep scene; highly acclaimed for his WAR series of white label releases, he's been championed by industry stalwarts including Youngsta and released tunes on labels Black Box, Osiris and Wheel & Deel. The Bristol-based DJ, also known as Peter Simon, can be found at venues across Europe, including at Caspa's infamous Dub Police event, and is regularly played on Rinse FM and BBC Radio.

Madd's musical output is now reaching back to the reggae-influenced dubstep sound, building up a diverse following who love the old school dubwise sounds with bone-shaking bass and the low end of the sonic spectrum. This fusion will be the main focus of his label, Roots & Future, which just launched earlier this year with more releases following soon.
