Dafydd's formative years were spent singing in church choirs in his home city of Liverpool, and later with the Liverpool Philharmonic Choir under Professor Ian Tracy. Since relocating to West Wales, to pursue a PhD in the alchemical writings of Thomas Vaughan (fl.1650), he has been active in DIY underground music networks since the early 90s. His projects since then synthesise his academic interest in hermeticism and sound.  His music has been released on labels in USA, Germany and Australia, played by John Peel, BBC Wales on Resonance FM. Biba Kopf in The Wire describes his music as “a fabulous delirium of competing frequencies”. He has collaborated with Toshimaru Nakamura to devise an object score deriving from Japanese ceramics. He received Sound and Music Composer Curator Award (2019) in 2019. Most recently he has devised a graphic score 'Unland' for flute, violin and harp for Richard Craig,  Angharad Davies & Rhodri Davies. He curates the experimental music and alchemy program Listen to the Voice of Fire and its Bandcamp music label releasing cassettes and cdrs. During Covid and lockdown Roberts devised, commissioned text and wrote a series of 3 chapbooks exploring  imaginal, hermetic and folk themes, each accompanied by a cassette release, and since 2019 Roberts has focused on developing sound and music relating to the (holy) wells of Tregaron and surrounding areas. He has devised site specific performance and scores for Angharad Davies and Rhodri Davies (Caerdroia), and with the Friends of the Well with Angharad Davies, supported by Ty Cerdd, 2025's Dol Awen Caron. Roberts runs the Tregaron based Gwyl Ffynnon Garon each March  bringing together experimental and folk idioms to a small and growing audience. Culture Colony has filmed the wells project from discovery, cutting back the overgrowth to performances at the well side.
