Leonidas has been played over 10 times on NTS, first on 12 November 2012. Leonidas's music has been featured on 11 episodes.

After 10 years of building his analogue studio and honing his craft, Leonidas debuted with “Sequential EP” in 2012 on his friend Kay Suzuki’s Round In Motion label, to acclaim from a broad range of musicians and DJs, from Manuel Gottsching to Theo Parrish and DJ Harvey (who included “Interstellar Vibrations” in his “The Sound Of Mercury Rising Vol 2” compilation in September 2019). Leonidas subsequently collaborated on 2 further vinyl EPs (Synqlock Vol I & II) with Kay Suzuki, to wide acclaim.

Leonidas is currently working on material for 2 albums, the debut album by Leonidas & Hobbes plus his own solo album, both of which will include collaborations with singers and songwriters, including E113 and Leo's partner Joanne.
