On April 12, 1991, DARK ANGEL released "Time Does Not Heal," their fourth studio album and a monumental testament to thrash metal extremity. The record famously contains 246 riffs across nine tracks, a staggering figure that demonstrated the band's obsessive commitment to compositional density. Drummer Gene Hoglan, whose technical brilliance earned him the nickname "The Atomic Clock," delivered one of the most impressive drumming performances in thrash history, executing impossibly complex patterns with mechanical precision. Guitarist Jim Durkin and Brett Eriksen crafted labyrinthine guitar arrangements that demanded repeated listens to fully absorb. Vocalist Ron Rinehart's aggressive delivery matched the instrumental fury note for note. Though DARK ANGEL disbanded shortly after this release, "Time Does Not Heal" stands as their crowning achievement, a record that pushed thrash metal to its technical limits and influenced generations of extreme metal musicians who followed in its wake.
