Manraze, the rock trio formed by Def Leppard’s Phil Collen, Girl’s Simon Laffy and The Sex Pistols’ Paul Cook, played its U.S. debut show on Oct. 2 at The Roxy in Hollywood, Calif.
Before the show, Manraze treated high school students to a private sound check through Grammy SoundChecks, a program devoted to teaching students about the music industry.
Watch the video below for a glimpse of the sound check, and take a look at Phil Collen cranking it up through his ultra powerful 5150 III cabs.
