Could it be some fresh tunes? Or perhaps an on-stage collaboration?

Anyone heading to the Pyramid Stage to see Kanye West's Glastonbury headline slot tonight may be in for a treat.

The US rapper is expected to debut some new music at the festival on Saturday night after producer Mike WiLL Made it hinted at the likelihood on his Instagram page.

West's next album SWISH (formerly So Help Me God) is due out later this year with featured vocals from Sia and Vic Mensa on "Wolves" and Paul McCartney on "Only One".

Artists regularly use big festival appearances to test our fresh tracks on fans so perhaps the Pyramid will host a special team-up from West and WiLL. One thing's for sure - West looks like he means serious business in the photo so anyone who signed the petition against his booking should prepare to be proved wrong. Providing he doesn't get drowned in wee that is.

Florence + The Machine headlined Friday night in place of Foo Fighters, who had to pull out after frontman Dave Grohl broke his leg falling off stage in Sweden. The Who will close this year's Glastonbury tomorrow night.
