Albarn's pop collective were criticised in some newspaper reports for their set at the event, with many comparing it unfavourably to his performance with Blur one year previously.
Speaking to Radio 1, the singer said: "We were yet to change the dynamic entirely from the cartoon band acting purely as a film orchestra into something that had more of a human element to it.
"Basically, the difference between that and the next gig we did at Roskilde [Denmark] which was the same-sized audience, same age demographic, was I just communicated with the audience more. It evolved. I introduced Bobby Womack, introduced Lou Reed, introduced anyone.
"I didn't take for granted that if these people were going to be at the front then there had to be some kind of human interaction. It evolved into something with more human interaction. I know what people were reacting to."
Gorillaz are currently on a world tour promoting their Plastic Beach LP.
