Frank Ocean's set at Lovebox may have been filmed by Spike Jonze.
The singer performed using some fantastic visuals, channelled by a team close to the stage.
Speculation immediately mounted that Spike Jonze was behind the camera work, with some even spotting the director down front.
Lovebox have yet to comment, but fans on Reddit have begun to discuss the possibility of a live document helmed by the famed director.
Here's a snap from a fan on the site.
If Thursday at Wimbledon was one of the best of my life, Friday is now also one of the best of my life, and I'm a bit worried I'm living in a virtual reality simulation! Here's Frank Ocean rather nearby singing so beautifully as one of my film heroes, Spike Jonze, films him and projects a live music video of it back to the stage. We had no chance of getting close to the main stage so had stayed by a platform in the middle because they were setting up some interesting rare cameras for the gig. It turned out to be the platform Frank performed on for the whole set. His voice was incredible, the night was warm and clear and the audience were sweet and sharing with one another. It was pure magic
