More than enough ink both real and virtual has been spilled on Iggy Pop throughout his ridiculously influential and lengthy musical career, and with the legend turning 70 next month, we should all enjoy him for as long as he’s here to kick ass. Additionally more than enough ink both real and virtual has been spilled on Metallica; so instead of discussing backstory and biography, I’ll say this: Metallica is currently on tour to support their latest album, 2016’s Hardwired . . . To Self-Destruct, and while on a several night run in Mexico City with Iggy Pop as an opener, the members of Metallica invited the legend on stage to play The Stooges‘ “T.V. Eye.”
