to the band; Rob Cannavino, who had been Gustafson's guitar technician, and Merritt Gant, formerly of Faith or Fear. Ellsworth stated in an interview with Invisible Oranges years later that the reason Overkill had hired two guitarists was mainly because they wanted to do something different: "We knew if we replaced Bobby with one guitarist, we'd get compared to what we were. So, it seemed like to logical thing to bring in two players. We didn't want anyone to say, 'Bobby was better than this new guy.' And we wanted to perform old stuff with two guitars to keep in fresh. We realized that change isn't a bad thing." The "new" Overkill recorded their fifth album Horrorscope, once again with Terry Date, in 1991. Featuring the furious riffs and trade-off solos of new guitarists Cannavino and Gant, and the refined songwriting of Verni and Ellsworth, Horrorscope quickly silenced worries from fans the band would not recover from their split with Gustafson. Today, the album is widely regarded as one of Overkill's defining moments and is arguably their heaviest release. Focusing on a darker, heavier style, the album spawned the doomy single "Horrorscope", a departure from the band's earlier singles, which had traditionally been uptempo songs. Horrorscope was also Overkill's first album to be accompanied by more than one music video or single; there were music videos for the title track and "Thanx for Nothin'" (both of which received some good airplay on Headbangers Ball), while other songs like "Coma", "Infectious" and the cover version of Edgar Winter's "Frankenstein" received particular attention (through radio or otherwise), therefore expanding the band's popularity in the heavy metal community, and helping the album enter the Top 30 on the Billboard Heatseekers chart. Overkill supported Horrorscope by touring North America with Anacrusis and Galactic Cowboys in 1991 and Armored Saint in 1992, after which Sid Falck left the band. Admittedly never a big fan of thrash metal music, Falck 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. Falck was replaced by former M.O.D. drummer Tim Mallare, with whom the next Overkill album I Hear Black was recorded. Released in March 1993, I Hear Black was produced by Alex Perialas (who previously produced their albums Taking Over and Under the
