Here’s a collaboration we never thought we’d be writing about, Peal Jam and Jay-Z.

The two acts joined forces for a performance of Jay-Z’s hit track 99 Problems as part of the Made In America festival which had been curated by the rapper.

The two day festival took place over the weekend and also saw performances from Passion Pit, Skrillex, Calvin Harris, Odd Future and Drake.

In an unexpected turn of events Jay-Z decided to join the rock band on stage during their set for the track before heading off as Pearl Jam moved into a performance of Rockin’ In The Free World.

Check out the performance above.
