After revolutionizing '90s rock as the maniacal, angsty frontman of Korn, nu-metal patriarch Jonathan Davis unleashed some nimble solo moves. His cuts for the Queen of the Damned soundtrack—particularly the haunted, Chester Bennington-sung "System"—presage the unsparing self-reflection of late-career tracks like the violin-sliced "What It Is" and the sitar-boosted "Basic Needs." Davis' guest-vocal turns also bring unexpected twists: He cuts straight through the grinding deathcore of Suicide Silence's "Witness the Addiction," while on Tech N9ne's hip-hop body slam "Starting To Turn," he's a mischievous inner voice encouraging havoc.
