Massive Attack were originally slated to headline the last night of festivities at Banksy’s pop-up “bemusement park” Dismaland, but after they pulled out, De La Soul closed out the proceedings with some help from a masked Damon Albarn, who came out to perform their 2005 Gorillaz collaboration “Feel Good Inc.” Watch below; Damon Albarn switches to a working microphone about 30 seconds in.
