UPDATE: The band have uploaded professionally-shot footage of their long-awaited "Spit Out the Bone" performance. Check it out above.
Metallica returned to London's O2 Arena last night amidst their U.K. tour behind Hardwired ... to Self Destruct. The Big Four thrashers' set doubled as a long-overdue christening for "Spit Out the Bone," a whip-lashing old-school epic off last year's LP that has since emerged as a huge fan favorite. Needless to say, diehards were on hand with cell phones out to capture the highlight's fiery debut. Consider it good old fashioned heavy-metal wish fulfillment.
