The album, produced by the band and Stephen Sedgwick, is due to be released on Christmas Day (December 25) as a free download.

It was recorded on an iPad during the band's North American tour in October and is described as a “sonic journal”.

"I did it because there's a lot of time that you just spend staring at walls essentially. And it was a fantastic way of doing it," Damon Albarn said.

"I found working in the day, whether it's in the hotel or in the venue, it was a brilliant way of keeping myself well."

'The Fall' will be available from Gorillaz.com. A physical release is due to be released in 2011.
