Pearl Jam took to the stage in Rome, Italy late last month, and while they performed a number of their own classics, they also managed to chuck in something a little different.
They tackled Kiss' Black Diamond, with guitarist Mike McCready and drummer Matt Cameron on the vocals.
Frontman Eddie Vedder introduced the track, telling the crowd: “I’m so excited. It’s not the first time in the history of the group, but it might only be the second. It’s a rare occurrence.”
