This damned band

"Motherfather are 1974's biggest rock act. They strike a pose of 'worshiping the devil' only to find that they're actually...worshiping the devil. It's one heavy trip, man. When Satan himself makes a cameo in their dressing room, everything seems to go to hell. Groupies go missing, relationships crumble, 'pharmaceutical representatives' come around to collect, and on top of all that, it turns out someone close to the band has been in league with Lucifer all along--but who? As told to a documentary camera crew, this is the story of their world tour...with the band's souls at stake,"--page [4] of cover.
