Addison Groove hosted a guest show on 27 February 2018. Addison Groove has been played on NTS over 110 times, featured on 115 episodes and was first played on 24 September 2012.

Initially known more widely for his dubstep alias, Headhunter, Antony Williams' footwork project as Addison Groove has quickly grown from a side-hustle to his main focus over the last few years. Melding Chicago footwork with jungle, dubstep and other UK bass-driven sounds, his output is known for its stripped-down drum machine beats, acid basslines and hip-hop / booty-leaning vocals. The Quietus has cited Addison Groove as being "instrumental in drawing Chicago juke and footwork within reach of UK dancefloors". His discography boasts releases on Swamp 81, 50Weapons, Tectonic, 3024, Gutterfunk and his own Groove imprint.
