Tool

Tool is an American rock band formed in 1990, noted for a progressive approach to heavy music that combines dense, textural guitar work, complex polyrhythmic drumming, and extended song structures. Their sound mixes heavy and atmospheric elements with Maynard James Keenan's distinctive vocals and often cryptic, introspective lyrics. Instrumental hallmarks include Adam Jones's sculpted guitar textures, Danny Carey's rhythmically adventurous drumming, and prominent, melodic bass lines; the band is also known for its elaborate visual presentation and carefully designed album artwork.
