As they have been doing for the last few years, Metallica members Kirk Hammett and Robert Trujillo do a nightly "doodle" jam on stage, while James and Lars take a little break. While performing in in Berlin, Germany on July 6 at Olympiastadion, the band thought the special occasion warranted a cover of a local band – namely Rammstein. The duo pulled out a decent cover of "Engel." The crowd was very supportive and even helped Trujillo sing the lyrics a bit.
