Video footage of drummer Lars Ulrich and the rest of METALLICA hanging out with New Orleans brass ensemble THE SOUL REBELS and playing THE SOUL REBELS trombone during a rehearsal for METALLICA's 30th anniversary week of concerts at The Fillmore in San Francisco, California in December 2011 can be seen below.

THE SOUL REBELS opened all four METALLICA 30th-anniversary shows and jammed with METALLICA every night. THE SOUL REBELS also played both days at METALLICA's Orion Music + More festival.

"They had never dealt with a brass band," THE SOUL REBELS snare drummer and co-founder Lumar LeBlanc told The Times-Picayune of his new buddies in METALLICA. "They accepted us as a band. They didn't want us to come in with 'When THE Saints Go Marching In'. They saw us as, 'Ya'll can actually do this METALLICA music.'"

THE SOUL REBELS released their Rounder Records debut, "Unlock Your Mind", on January 31.
