Spectrum of Death

Spectrum of Death is actually a reissue of the band's 1988 demo Lock Up Your Children, which was licensed by Edge Entertainment to Mexican label Avanzada Metálica, who re-released it as a full-length studio album under the title Spectrum of Death in 1989;[2][3][4][5] however, the album was not released in other territories until years later.[6] It was recorded at Opus Recording (later known as Wave Digital once they removed the 2 inch tape machines in favor of Akai Digital Audio Machines) in Gurnee, Illinois. It was produced by Eric Greif and engineered by Al Pangeliron.

Spectrum of Death is often hailed as one of the best thrash metal albums ever made, as well as one of the fastest and most abrasive in the genre; which led Morbid Saint being compared to other thrash metal bands like Kreator, Slayer, Sadus, and Demolition Hammer.

All songs on Spectrum of Death are published by Griffy Guy Publishing (BMI).
