Metal Messiah.

A bizarre sci-fi rock opera like little else being produced under the banner of Canadian film at the time, Metal Messiah is about an enigmatic metallic-skinned stranger trying to stop society's self-destructive obsession with rock and roll. Anchored in Toronto's live music scene if the late 1970s, this dystopian parable was the feature film debut of local music impresario and director Tibor Takács. Working with screenwriter Stephen Zoller, Takács' film is a crudely crafted, episodic work that plays out like a glam version of Amos Poe's avant-punk NYC flick The Foreigner (1978), but with even more ambition, attempting to scale to the bombastic rock opera heights of films like Phantom of the Paradise (1974) and Tommy (1975).
