Lady Gaga, who will release ARTPOP November 11, took the stage to kickoff the iTunes Festival with an hour-long show at London's Roundhouse on Sunday, 1 September. She performed seven tracks from the album, including a debut of Jewels & Drugs, which features the singer rapping for the first time alongside Twista, Too $hort and T.I.

The star opened with a song called Aura, wearing what's described as a "black ninja-style suit" and ski mask before stripping down to glittering boots and a bra, the first of several costume changes. She later performed MANiCURE, Sex Dreams, Swine and finished the set with her latest single, Applause.
