Korn made an enormous impact with this 1998 opus: On hits like “Freak On a Leash,” they practically turned nu-metal into a household name as frontman Jonathan Davis comforted the alienated with his feral vocal tics over downtuned guitars and hip-hop-style grooves. The band’s frenzied versatility shows through in slow-burner “Justin,” with Head and Munky extracting crunches and squeals from their guitars, while Ice Cube’s appearance on “Children of the Korn” lends street cred to the band’s freakiest rap-rock urges.
