Backstage with Metallica's Lars Ulrich / Photo by Andrea Labarge

Sure, it was pandemonium when Metallica took the stage at L.A.'s Wiltern last night. Playing a venue about one-tenth the size of their normal touring abodes, the band powered through a classic-laden set and surely melted some faces (read our review).

But before the chaos, SPIN.com headed backstage and caught up with Lars Ulrich and Flea, speaking to both about their participation in last night's event, which benefited the Silverlake Conservatory of Music, a music school that Flea helped found. We asked both about the role music played in their lives as kids, and how they, in turn, influence young musicians today.
