Tool established themselves as one of America’s most enduring and unpredictable acts with an ever-evolving brand of muscular but mind-altering sonics, a wry sense of humor, and a mystical aesthetic that attracted a cult-like following of devoted fans with just a handful of albums spread across decades. Their greatest breakthrough was to meld dark underground metal with the ambition of art rock, crafting multi-sectioned, layered songs as if they were classical composers. While embracing the artsy, they also paid musical homage to the relentlessly bleak visions of grindcore, death metal, and thrash. Even with their post-punk influences, they executed their music with the sound and feel of prog rock, alternating between long, detailed instrumental interludes and lyrical rants in their songs. Debuting in the early ’90s with Undertow, they were initially lumped in with the nu-metal contemporaries of the time, which made them a hit on rock radio with their sophomore effort, 1996’s Ænima. However, they soon broke away from those associations, evolving beyond the confines of traditional song structures and song lengths, crafting epics that often clocked in past the ten-minute mark on LP head-trips Lateralus (2001) and 10,000 Days (2006). After a lengthy 13-year hiatus, they returned to the fold in 2019 with their fifth opus, the chart-topping, Grammy-nominated Fear Inoculum. In 2022, they celebrated their 30th anniversary with ‘Opiate²,’ a re-recorded version of their debut single.
Formed in Los Angeles by percussionist Danny Carey, guitarist Adam Jones, vocalist Maynard James Keenan, and original bassist Paul D’Amour, Tool had a knack for conveying the strangled, oppressive angst that the alternative nation of the early ’90s claimed as its own, which helped them slip into the scene during the post-Nirvana era. Buffered by a prime slot on the third Lollapalooza tour in 1993, their debut full-length album, Undertow (Zoo Entertainment), rocketed to platinum status. Fervor for the band even resurrected their first effort, 1992’s Opiate EP, on the Billboard charts. While they were in the studio recording a follow-up, D’Amour amicably parted ways with Tool and his spot was filled by Justin Chancellor. By the time the fresh quartet delivered their sophomore album, Ænima, in late 1996, the alternative rock mainstream was ready. The album shot to number two on the Billboard charts and was certified multi-platinum in less than a decade. Singles ‘Stinkfist,’ ‘Forty Six & 2,’ and the Grammy-winning title track were all Top Ten hits on the U.S. Rock chart, boosted by the twisted and often disturbing music videos created by Jones. After a co-headlining slot with Korn on Lollapalooza ’97, Tool remained on the road, supporting Ænima into the next year.
As nu-metal established its mainstream dominance at the close of the decade, Tool returned to the shadows. During their hiatus, Keenan formed a side project with former Tool guitar tech Billy Howerdel. A Perfect Circle debuted in 2000, and their album Mer de Noms was a surprise hit. Their ensuing tour was a sold-out success as well, which only served to fuel Tool breakup rumors. To quell the speculation, they issued the stopgap B-sides/DVD set Salival late the same year. Meanwhile, in the studio, the band continued to journey down a new path that further distanced them from the mainstream. Delving deeper into their own mythos, songs grew longer, lyrics more inscrutable, and artwork increasingly psychedelic. Though they retained their pummeling, metal-oriented base, the quartet smashed the formula by further experimenting with complex time signatures, expansive atmospherics, and a classical approach to song compositions. The first taste of 21st century Tool arrived in January 2001 with the Grammy-winning single, ‘Schism,’ which was also their first song to chart on the Hot 100. Lateralus (Volcano) arrived that May, topping the Billboard 200. Subsequent singles ‘Parabola’ and ‘Lateralus’ were favorites on the U.S. Rock charts, and the album soon went multi-platinum.
