After releasing the now-timeless classic “Consuming Impulse” in 1989, PESTILENCE was faced with the necessity of replacing a notable member – vocalist Martin van Drunen – following his departure to pursue a career with Asphyx. The band found themselves at the crossroads with an uneasy task, given the success brought about by “Consuming Impulse”. As it turns out, the decision to revert to Patrick Mameli as vocalist not only stood the test of time, but, in hindsight, gave birth to a trademark ingredient of PESTILENCE’s core sound formula. To make things even more interesting, Mameli stepped away from playing bass – from now on assuming the double role of guitarist vocalist –  and enlisted Tony Choy (of Cyinc at the time), adding another famed name to the line-up, and another anchor point for the band’s inventive nature. Alongside Patrick Uterwijk (guitars) and Marco Foddis (drums), they recorded “Testimony of the Ancients” (1991) at the legendary Morrissound Studios (USA), where it acquired a refined production, courtesy of Scott Burns.
