Tye Trujillo already knows a bit about the rockstar lifestyle — his dad is Metallica bassist Robert Trujillo — but he’s about to find out more: The 12-year-old is filling in as bassist for Korn’s Reginald “Fieldy” Arvizu, who won’t be available for the South American leg of the band’s tour.

Trujillo is a member of California band The Helmets, and he’ll be playing with Korn until May 6.

“We are bummed Fieldy can’t join us on this run,” Korn said on their Facebook page, “but excited to do a few gigs with a young player like Tye. We look forward to welcoming our brother Fieldy back when we return to the States in May.”
