Editor’s Note: A little before Gorillaz hit the stage last night (July 12) at the Blue Hills Bank Pavilion, Carly Simon posted a photo of her and Damon Albarn shooting the breeze backstage. It fueled some speculation that Simon, who guests on Gorillaz’ recent album Humanz would join the boys onstage at the Boston venue. It didn’t take long for that to come to fruition, as she shocked the rain-soaked crowd to join the animated British collective to perform “Ticker Tape.” Vince Staples also joined in on the Gorillaz action, coming out after his opening set to drop verses on “Clint Eastwood.” There were a lot of rewards for a crowd who endured some intense rain and thunderstorm action down by the Seaport, and while they didn’t have sunshine in a bag, the music shined through. Vanyaland’s Eddy Leiva was under the big tent to capture some visuals of the show, including Simon’s appearance, and you can scan through his full gallery below.
