TOOL

Tool formed in Los Angeles in 1990 and built a body of work that joins heavy music with long-form arrangements, visual art and themes of personal evolution. The band consists of vocalist Maynard James Keenan, guitarist Adam Jones, drummer Danny Carey and bassist Justin Chancellor, who joined in 1995 after replacing founding bassist Paul D'Amour. Tool has won four Grammy Awards, toured internationally and produced albums that have topped charts in several countries.

After issuing the EP Opiate in 1992, Tool released its first studio album, Undertow, in 1993. The record presented a more classic heavy metal sound, arriving during the early-1990s alternative-rock era. With 1996's Ænima, the group shifted toward the alternative metal and progressive metal approach that became central to its later work. The album helped make Tool a major act in both movements.

The band expanded its musical and visual ambitions on Lateralus (2001) and 10,000 Days (2006), records that combined intricate instrumental writing with lengthy compositions and received critical acclaim alongside international commercial success. Its music has also been associated with progressive rock, psychedelic rock and art rock. Adam Jones has contributed to the group's visual presentation, while artist Alex Grey has created album artwork for the band.

Tool's relationship with the music industry has at times involved censorship and an insistence on privacy. On August 2, 2019, its catalog became available for digital streaming and purchase after years of being withheld from such services. The fifth studio album, Fear Inoculum, followed on August 30, 2019, earning widespread critical acclaim. Before its release, Tool had sold more than 13 million albums in the United States alone.
