Horrorscope (original working title - "Bare Bones") is the fifth studio album by American thrash metal band Overkill. Released in 1991 on Atlantic Records, it was their first album to feature the guitar duo of Merritt Gant and Rob Cannavino.
Following the loss of long-time guitarist and songwriter Bobby Gustafson, Overkill added two new guitarists to the band; Rob Cannavino, who had been Gustafson's guitar technician, and Merritt Gant, from the New Jersey thrash band Faith Or Fear.
Overkill recorded Horrorscope in 1991 with Terry Date as producer.
In 1992, during the Horrorscope tour, Sid Falck left the band. Admittedly never a big fan of thrash metal music, Sid said that he had initially wanted to push his drumming to the limit by playing the most complex type of music (of the era), and in time he decided to pursue other musical interests. He was replaced by former M.O.D. drummer Tim Mallare.
