Steroid Maximus has been played on NTS in shows including OnoTesla, featured first on 16 June 2018. Songs played include Life In The Greenhouse Effect.

Steroid Maximus is the instrumental side of the man behind the Foetus moniker, J.G. Thirlwell. Whereas Foetus itself covers a wide spectrum of combining and mutating different styles, Steroid Maximus is even more varied with different styles and sounds being mixed together. Industrial beats, big band horns, world music, 70's funk -- all this and more being cohesively united by the compositions of Thirlwell.

On his Steroid Maximus releases, Thirlwell tended to work with collaborators, unlike his Foetus work. For example, 1991's Quilombo featured Lucy Hamilton, Away, Hawn Rowe, Lin Culbertson, and Raymond Watts.

Side note: Thirlwell composes the music for the Adult Swim cartoon "The Venture Bros.". The pilot episode featured snippets from both Foetus and Steroid Maximus tracks. "The Venture Bros." opening theme is actually an abridged version of the Steroid Maximus track "Fighteous".
