Most bands were satisfied with being popular in the underground scene, Flotsam and Jetsam decided to take a step further and record an album aimed for the mainstream. "Cuatro", F&J's fourth full-length release, was precisely that album. The record proved that a thrash metal band can achieve success even on a bigger scale while still staying true to their roots. "Cuatro" - the band's fourth full-length album, was released in October 1992. The production is top notch - "Cuatro" is by far one of the best sounding thrash metal albums ever recorded. Producer Neil Kernon took a different, more straightforward approach resulting in a sharp, detailed sound, polished to perfection.
