The longest track on the album (over seven minutes), "Flood" is a precursor to the progressive epics Tool would write later. The song builds from a single, repeating bass note over a maelstrom of weird studio effects, eventually morphing into a crushing riff about the sinking feeling of being overwhelmed by society. "This ground is not the rock I thought it would be," Keenan concludes—a perfect summary of the album’s disappointment with reality. tool band undertow
