BIOGRAPHY: TOOL

Tool's greatest breakthrough was to introduce dark, vaguely underground metal to the preening pretentiousness of art rock. Or maybe it was introducing the self-absorbed pretension of art rock to the wearing grind of post-thrash metal -- the order really doesn't matter. Though Metallica wrote their multi-sectioned, layered songs as if they were composers, they kept their musical attack ferociously at street level. Tool didn't. They embraced the artsy, faux-bohemian preoccupations of Jane's Addiction while they simultaneously paid musical homage to the dark, relentlessly bleak visions of grindcore, death metal, and thrash. Even with their post-punk influences, they executed their music with the ponderous, anti-song aesthetic of prog rock, alternating between long, detailed instrumental interludes and tuneless, pseudo-meaningful lyrical rants in their songs.

Tool, however, had a knack for conveying the strangled, oppressive angst that the alternative nation of the early '90s claimed as its own. So, the band was able to slip into the definition of alternative rock during the post-Nirvana era, landing a slot on the third Lollapalooza tour in 1993, which helped their first full-length debut album, Undertow, rocket into platinum status. By the time the band delivered their belated follow-up, Ænima, in 1996, alternative rock had lost its grip on the mainstream of America, and their audience had shaped up as essentially metal-oriented, which meant that the group and the record didn't capture as big an audience as their first album, despite debuting at number two on the charts. After a co-headlining slot with Korn on Lollapalooza '97 wrapped up, Tool remained on the road, supporting Ænima until well into the next year.

During their usual extended hiatus between albums, Maynard James Keenan decided to use his downtime productively by forming a side project, dubbed A Perfect Circle. The band's 2000 debut, Mer de Noms, was a surprise hit, while their ensuing tour was a sold-out success as well. With Tool breakup rumors swirling, the band put the speculation to rest by re-entering the recording studio and issuing the stopgap B-sides/DVD set Salival late the same year. Finally, May 2001 saw the release of Tool's third full-length release, Lateralus, which debuted at the number one position on the Billboard album chart and became the band's biggest hit. After the obligatory several-year sabbatical to pursue other projects, the group returned with another chart-topper, 10,000 Days, in 2006.
