Lady Gaga has been in London getting ready for the iTunes Festival on Sunday and from the looks of this just-released rehearsal footage, Mother Monster has been hard at work!
Gaga tweeted out the video out last night, which included a preview of her new song "Swine," which she will be debuting at the festival.
In the footage, Gaga is totally going for it, playing drums, headbanging and even reaching over to play the keyboard with her free hand.
We have to say, this reminds us a LOT of the old Gaga, who used to perform as part of Lady Gaga and the Starlight Revue before she got her big break.
Check out the rehearsal footage above to hear the new song, then watch the video below of Gaga performing with Lady Starlight at Lollapalooza in 2007 and tell us if you get deja vu, too!
