Lady Gaga has teased a new track, 'Swine', from her 'ARTPOP' album.
The singer posted a video of her rehearsing for her opening performance at the iTunes festival in London on Sunday (01.09.13) - where she has promised to perform an hour of new material.
In the video she juggles between playing a keyboard and a drumkit, and is flanked by five other musicians. The song starts slowly with just Gaga at the keyboard, singing: "I know, I know, I know, you want me / You're just a pig inside a human body / squeal out, squeal out, squeal out / You're so disgusting, / Swine."
The song then launches into a guitar solo before turning into a thumping glam pop number. In video overlays Gaga can be seen thrashing at her mini drumkit and keyboard and shouting "swine" again.
The song is the third to be heard from the 'ARTPOP' sessions after single 'Applause' - which was rush released after it started to leak on the internet - and a song rumoured to be called either 'Burqa' or 'Aura', which appeared to be leaked in demo form, but was quickly taken down.
Gaga has also confirmed she has recorded a follow up to her 2009 single 'Telephone' for the record, as well as a track paying tribute to Donatella Versace, called 'Donatella'.
Gaga has also made some unusual requests to her fans for what to wear to the iTunes show, writing on Twitter: "I will be providing a list of acceptable attire for #SwineFest throughout the week.
"Item 1: Seashells. Item 2: Seahorses 3: Starfish. I would also suggest 4. Paint colored dreadlocks for securing 'under the sea' Boticelli-Punk accessories."
