Steroid Maximus is the instrumental side project 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.
