Glastonbury Festival kicked off this week in Pilton, England and James Blake was one of the headliner performers last night. His set was full of songs off his latest album, The Colour in Anything, as well as older favorites. During his time, Blake brought out two surprise guests. First up was Vince Staples, who helped Blake perform his song, “Timeless,” by adding a verse. Luckily, this won’t be the last time the two are collaborating together. Staples told Fader that Blake has production credits on his upcoming Prima Donna EP.

Later on, Blake brought out Bon Iver’s Justin Vernon. The two performed their The Colour in Anything track, “I Need a Forest Fire.” Watch footage of that below, and his performance with Staples above.
