It may be that 2019 was the best year for ’90s metal since, well, 1999. Bands from the decade of Judgment Night re-emerged with new creative twists and tweaks: Tool stretched out into polyrhythmic madness, Korn bludgeoned with more extreme and raw despair, Slipknot added a new drummer (Max Weinberg’s kid!) who gave them a new groove, and Rammstein wrote an anti-fascism anthem that caused controversy in Germany (and hit No. 1 there too). Elsewhere, icons of the era returned in unique ways: Nine Inch Nails’ Trent Reznor scored a superhero TV series, Primus’ Les Claypool teamed up with Sean Lennon for some quirky psych rock, and Faith No More’s Mike Patton made an avant-decadent LP with ’70s soundtrack king Jean-Claude Vannier. Finally, the soaring voice of Linkin Park’s Chester Bennington returned for a moment thanks to Lamb of God guitarist Mark Morton, who released a song they recorded together in 2017.
