Tool is an American rock band from Los Angeles. Formed in 1990, the group's line-up includes drummer Danny Carey, guitarist Adam Jones, and vocalist Maynard James Keenan. Justin Chancellor has been the band's bassist since 1995, replacing their original bassist Paul D'Amour. Tool has won three Grammy Awards, performed worldwide tours, and produced albums topping the charts in several countries. Due to Tool's incorporation of visual arts and very long and complex releases, the band is generally described as a style-transcending act and part of progressive rock, psychedelic rock, and art rock.
