Watch Metallica Pay Tribute to Martin Eric Ain With Thundering Celtic Frost Cover

Kirk Hammett, Robert Trujillo ripped through "Procreation (Of the Wicked)" in late bassist’s honor

Metallica wrapped up the latest European leg of their "WorldWired Tour" in Geneva, Switzerland, last night, April 11th. As with previous stops, the Big Four thrashers' performance found guitarist Kirk Hammett and bassist Robert Trujillo forgoing the band's usual mid-set break to cover an artist hailing from that night's city. This time around, they paid tribute to Celtic Frost's pioneering late bassist, Martin Eric Ain, with a fiery "doodle" of the icons' "Procreation (Of the Wicked)," which appeared on the Swiss band's 1984 debut Morbid Tales.

"Tonight, we pay tribute to the Swiss band Celtic Frost," Trujillo declared beforehand. "This is in memory of Mr. Martin Eric Ain, bass player extraordinaire, and this song is called 'Procreation' — you know the rest. Sing it with me, or headbang like it's 1984!"

Prior to the Geneva show, Trujillo and Hammett paid tribute to several German rockers, taking on Peter Schilling's "Major Tom (Coming Home)," Michael Schenker Group's "Into the Arena," and UFO's "Rock Bottom" at their gigs in Stuttgart and Hamburg. Last year's U.K. trek saw them covering Black Sabbath's "War Pigs" (in Birmingham) and Oasis' "Don't Look Back in Anger" (in Manchester).

Metallica have just over a week to take a breather before they return to the stage at San Francisco's AT&T Stadium for the San Francisco Giants' sixth-annual "Metallica Night." After that, they'll embark on another European leg, followed by a North American arena tour in autumn; check out the full itinerary here. The group's remastered 5.98 EP: Garage Days Re-Revisited drops tomorrow, April 13th through all major outlets, as well as band's official website.
