This week's new events

AR Rahman: Jai Ho – The Journey Home, London Warning! Anyone who salivated over Slumdog Millionaire is about to risk a heart attack. The man behind the score, AR Rahman, will be putting his world tour to bed in London. And with creative director Amy Tinkham – who helped turn the Backstreet Boys, Britney Spears and Mariah Carey into teenybop royalty – behind the scenes, this should remind you how spectacular contemporary Indian music can be. With material spanning his career, the show will be garnished with ever-changing sets, huge LED screens and dancers from all over the world. Jai Ho indeed! O2 Arena, SE10, Sat; Wembley Arena, HA9, Sun JP Watson Stockton International Riverside Festival Whether it's whirling dervishes roaming the streets, a game of gangsta Scrabble, floodlit boxing, or a pianist launching himself into space, SIRF promises to put a bit of oomph on to the banks of the Tees. A particular coup is Rosenberg and Requardt's acclaimed voyeuristic dance spectacle Electric Hotel, and look out too for I Spy, a public procession through Stockton, before French pyrotechnicians Les Commandos Percu blast an array of gold and scarlet flames into the sky for their finale, Bombs Per Minute. Oh, and everything's free.
