Rocktober Blood is a 1984 horror film, directed by Beverly Sebastian and starring Tray Loren, Donna Scoggins and Cana Cockrell.
In an enigmatic move, Billy kills Kevin by slitting his throat and impales Mary on a wall-mounted coat peg.
A mysterious figure then appears in a Halloween "death" mask, and tells Lynn to meet with Chris, the band's manager, in the office.
When she arrives in the office, she is cornered by Billy, in the same death mask, who leaves her curled up, and crying on the floor.
John tells Lynn that the people he killed valued Billy more than him, even though he wrote the renowned songs himself.
On the tracks written and performed by Sorcery, Nigel Benjamin sang three songs: "Killer on the Loose," "I'm Back" and "Watching You."
