Watch Metallica, Rob Halford Tear Through "Rapid Fire" at Golden Gods 2013

The fifth Revolver Golden Gods Award Show in Los Angeles featured a headlining performance from heavy-metal legends — and 2013 Ronnie James Dio Lifetime Achievement Award receipients — Metallica. Naturally, James Hetfield and Co. showed their appreciation by melting their audience's faces off with a career-spanning blitzkreig, but they also made time to honor one of their forebears: specifically Judas Priest frontman Rob Halford, who joined the band onstage to perform the Judas Priest classic "Rapid Fire."
