Tool

Tool, formed in 1990 in Los Angeles, is one of the most influential bands in modern rock, known for their intricate and experimental sound. The band consists of vocalist Maynard James Keenan, guitarist Adam Jones, drummer Danny Carey, and bassist Justin Chancellor (who joined in 1995). Tool's music is characterized by complex time signatures, lengthy tracks, and philosophical and introspective lyrics, often exploring themes of consciousness, spirituality, and human experience. Their albums, such as Ænima (1996), Lateralus (2001), and Fear Inoculum (2019), have been critically acclaimed, with Lateralus being particularly noted for its Fibonacci sequence-inspired title track. Tool's live performances are also renowned for their visual artistry, incorporating elaborate stage designs, video projections, and a focus on the music over showmanship. The band's reluctance to conform to industry norms and their enigmatic approach have cultivated a dedicated fan base and solidified their place as pioneers in progressive metal and rock.
