Fresh from leaving the UK where Metallica an epic rendition of 'Master of uPuppets' in the poring rain (If you haven't seen it, watch it here now, it's damn good), the thrash metal legends performed in Germany, whipping out an epic cover from a hometown band.
The band's mid-set "doodle" saw bassist Rob Trujilio and guitarist Kirk Hammett perfrom a cover of Rammstein's "Engel" - two days after Rammstein played in the exact same stadium.
Rob even sang in German with help from the crowd who where obviously loving it.
Check out fan-shot footage of their cover below:
