The Blur/Gorillaz frontman told Jonathan Ross: "I thought it was rubbish… the intention was good but it left everyone with an empty feeling. It should have been more of a celebration.
"What did it achieve? What kind of feeling is sent out to the world when the world watches it and doesn't see anyone from Africa there?"
Albarn is not alone in feeling underwhelmed: others to have criticised the event include Elton John, David Gray and even the organiser, Midge Ure.
