Eyeless comes from Slipknot's self-titled debut album, released in 1999 by the Iowa-based masked metal band. Built around aggressive riffs and Corey Taylor's confrontational vocal delivery, the track helped define the band's early nu-metal sound and quickly became a live favourite. As Slipknot grew into one of metal's biggest acts, the song spread beyond albums and concerts into fan videos, workout playlists and short-form edits. Its raw opening still makes it an easy shorthand for intensity, anger and high-energy metal.
