The clip kicks off with Pert asking his co-conspirators if they'd like to make "a little more noise" and then Pert and Carey launch into the rhythms, eventually filled in by Copeland on guitar, Scannell on bass, Stone on percussion and Pert's words echoing in the background.

On the video's YouTube page, Copeland explains that a few days later more musicians came by to fill in horns and eventually the piano came as an afterthought.
Copeland's Super Grove jams have been going on since 2008, as Rolling Stone reports, when the Police reunion tour ended. He's played with Ben Harper, Primus' Larry LaLonde and Les Claypool, System of a Down's Serj Tankian, Taylor Hawkins of Foo Fighters, Snoop Dogg as "Snoop Lion" and many more in this time.
