Beady Eye will release their debut track 'Bring The Light' as a free download at 10am tomorrow (10.11.10).
The song is the first post-Oasis track to be released since the group split last year, and features four out of five members from the final line up of the band.
The announcement comes a day after the rockers released a 21 second video clip showing the group - Liam Gallagher, Gem Archer, Andy Bell and Chris Sharrock - in action, accompanied by a guitar riff.
Beady Eye have also reportedly completed their debut album, with The Rolling Stones producer Steve Lillywhite, in London, which is scheduled for next year.
Liam - whose fallout with brother Noel, the fifth member of Oasis, caused the band's split - has previously said he expects the guitarist and songwriter to "come crawling back very f***ing soon" after the band is unveiled.
Meanwhile Oasis' former manager, Alan McGee, said he's "pretty sure" Oasis will get back together in a few years.
He said to BBC Six music: "I mean, they're brothers. It's like, I've fallen out with my sister before and we're best mates now. Why are brothers gonna be any different?"
He also told how he's heard some of Noel's solo demos, which he is reportedly also preparing for an album next year.
He added: "Noel's demos are absolutely amazing. Totally amazing. The reason that guy is quiet is he knows what he's got up his sleeve."
