Trujillo — who has his own band, The Helmets — will be playing with Korn until May 6. Show Full Article Trujillo, the son of Metallica bassist Robert Trujillo, was recently named a temporary replacement for Korn’s current bassist, Reginald “Fieldy” Arvizu, who can’t make the South American leg of the band’s upcoming tour. And as you can see from the clip of him performing with drummer Ray Luzier (above), Trujillo can more than hold his own on stage. The 12-year-old started his new gig as Korn’s (temporary) bassist Monday evening when he joined the band for their Bogota show. Korn released The Serenity of Suffering, their 12th studio album, last year. Tye Trujillo is officially on the job.
