For his PhD at Goldsmiths, Richards researched the work of Daphne Oram, culminating in a functional build of Mini Oramics, which the British electronic music pioneer conceptualised over 40 years ago but never realised during her lifetime: a machine that can translate drawings into sound and compositions.

Richards' own output often features textured, evolving, polyrhythmic improvisations. He has performed and shown works throughout the UK – including Tate Britain and the Queen Elizabeth Hall – in the USA, Germany, Peru, Japan, and Sweden.
