Horror Show is a concept album based on many infamous monsters. Drawing from legend, literature, film, and perhaps even real life. A cover of Iron Maiden's Transylvania was recorded as well, which will be included on a limited edition first pressing of the album on a bonus disc that also contains an exclusive interview with Jon Schaffer and a cover of Iron Maiden's Transylvania.
