Virtual band Gorillaz rock festival
Gorillaz took top billing with an audio-visual spectacular on the first night of Glastonbury.
Radiohead's Thom Yorke and Jonny Greenwood also made a surprise appearance to celebrate the festival's 40th anniversary.
"Virtual band" Gorillaz, led by Damon Albarn, were replacing Irish rockers U2, who were forced to pull out after lead singer Bono injured his back.
Albarn was joined on stage by special guests including gangsta rapper Snoop Dogg, Madchester pioneer Shaun Ryder and The Fall's famously grumpy frontman Mark E Smith.
It was the Blur frontman's second Glastonbury headline slot in as many years after reforming Blur for a triumphant gig at last year's festival.
An energetic Albarn ran through all their hits, including Feel Good Inc and Clint Eastwood, as the cartoon characters of the virtual band came to life on a huge screen towering above the actual musicians on stage.
Once over the set divided opinion.
Dev Solomon, 29, from London said: "My girlfriend loved it and musically it was superb.
"But it was clunky. It did not feel very warm or like the band or the special guests were having fun. They left the hits too late and people did start getting bored.
"When they played them though it was great but festival crowds want to singalong all the time."
