Horrorscope is the fifth studio album by thrash metal band Overkill, released on September 3, 1991 through Atlantic and Megaforce Records. It was the first Overkill album to feature the duo of guitarists Merritt Gant and Rob Cannavino, and also the last to be released through Megaforce; although they remained on Atlantic until 1995.
Following the loss of longtime guitarist and songwriter Bobby Gustafson, Overkill added two new guitarists in Cannavino (who had been Gustafson's guitar technician) and Gant (previously from thrash metal band Faith or Fear). Sid Falck left the band during the Horrorscope tour in 1992, being replaced by former M.O.D. drummer Tim Mallare.
AllMusic's Eduardo Rivadavia gave the album a positive review, awarding it 4.5 stars out of five and stating, "The insecurity felt among Overkill fans by the departure of founding guitarist and key songwriter Bobby Gustafson in 1990 ultimately proved unfounded when the New York thrashers' expanded two-guitar lineup—featuring Rob Cannavino and Merritt Gant—arguably delivered the finest effort of the group's career in 1991's Horrorscope."
Horrorscope reached #29 on the Billboard Heatseekers chart in 1991. As of 2010, it remains Overkill's best-selling album of the SoundScan era, having sold over 120,000 copies in the United States. In a 2013 article by WhatCulture!, the album was ranked fourth on their list of "10 Greatest Thrash Metal Albums of All Time".
