"We have this phrase in Metallica land, which is 'no-brainer,'" drummer Lars Ulrich told Spinner backstage of why the band returned to the stage after a near four-year absence at a benefit for the Silver Lake Conservatory, a music school for kids, spearheaded by Red Hot Chili Peppers' Flea. "It's for Flea and it's for inner-city, underprivileged kids who need access to instruments and to be around musical education," he expounded.

Flea, who is presently teaching at the school once a week, has seen the support in the music industry rise -- from having Tracy Chapman play the first benefit, to Patti Smith -- and saw the biggest event yet for the school on Wednesday night. "We keep getting more intense," Flea told Spinner. "Tracy, Patti's pretty intense and Metallica's the most intense. We're gonna have God himself. Next year, Jesus is gonna come back," he joked.
