During rehearsal, Lee asked if he could play “Bliss of Evil”, a popular song from the Prom Night setlist. The group refuses at first, but Isla tells them to go, everything will be okay with her. They played the song and Isla collapsed, panting and sweat running down her face. Nic comforts her while no one in the group tells Lee what is going on or why Isla is panicking. Suddenly, someone’s throat was slit while another’s skull was crushed. Survivors later discovered that the escape door had been chained shut. Throughout the night, the remaining members of the group are stalked by the horrifying hooded killer Bloodface (Corrie Hinschen). The gym walls are soundproofed to drown out screams, but can they also be blood-proof? With Bliss of Evil, Morris surpassed the previous heights in the rock and roll horror sub-genre achieved by cult favorite Green Room. This is achieved through an expert blend of suspense elements within the slasher formula. Here, Morris turns the tables by having the slasher follow the principles of the suspense picture, trading off body count to create tension throughout the story. Additionally, the mystery surrounding Isla’s injury keeps the audience’s interest focused on something other than the impending murders. Instead of weakening slasher traditions, Morris uses thriller elements to enhance them.
