The fresh rehearsal footage shows Gaga singing on stage flanked by a trio of backing dancers while a rock-flavoured song plays over the sound system. It follows an earlier rehearsal video in which the singer previewed a new track called ‘Swine’.

Gaga is set to open this year’s iTunes Festival with a performance at London’s Roundhouse on September 1 – her first gig since February, when she was forced to cancel a slew of tour dates while she underwent surgery for a hip injury – and she has hinted that she will be joined by a surprise guest at the show.

The singer was asked if her forthcoming album ‘ARTPOP’ features any collaborations and remained tight-lipped before adding: “At iTunes at the Roundhouse we will be revealing one of the collaborations that we’re doing and I’m excited for everyone to see that.”

She also recently reassured fans fans that a sequel to her memorable 2010 video ‘Telephone’ is “surely coming” and revealed that she will perform the hit during her Roundhouse show.

Earlier this month, Lady Gaga unveiled the video for the first single from ‘ARTPOP’, ‘Applause’, which features shots of the singer’s head on the body of a swan. ‘ARTPOP’ is due for release on November 11 and features production from Zedd, Madeon and DJ White Shadow.
