Korn is a hard-rocking metal band ... with a 12-year-old bassist, at least for a brief time. The pre-teen in question, Tye Trujillo, is the son of Metallica bassist Robert Trujillo. He'll be filling in for Korn's regular bassist, Reginald “Fieldy” Arvizu, during the South American leg of the band's tour because Arvizu isn't available, Entertainment Weekly reports. The band starts the South American run of shows April 17, it explains on Facebook, and will be back in the States with Arvizu on hand in May. (More heavy metal stories.)
