Electro-house hit machine Guetta returns to the iTunes Festival, armed with a sackful of chart-topping AutoTune anthems. There'll be mass sing-alongs, maniacal screaming, manufactured euphoria and plenty of heart signs in the air from the glossy-haired superstar DJ – plus, to his credit, a hot-damn impressive stage show with intergalactic dancers and an explosion of LED lights across his four decks ’n’ FX set-up. It's pure cheese – but, as you'd hope from a Frenchman, pretty tasty cheese. Support comes from classical/electronic chartbusters Clean Bandit, plus Robin Schulz.
