Undertow

Tool's first full-length album, 'Undertow' marks a significant progression from their debut EP, showcasing a more mature and atmospheric sound. The album blends the aggression of alternative metal and grunge with the complex song structures of progressive rock, creating a dark, heavy, and immersive listening experience. Defined by its dynamic shifts, intricate musicianship, and Maynard James Keenan's visceral lyrics and vocal delivery, 'Undertow' established the band as a major force in 90s heavy music.
