Noel Gallagher revealed he was re-recording 14 tracks that failed to make it on to the band’s previous records.
Despite the bad blood between the siblings, Noel said he has an emotional connection with the tracks.
He added: “I’ve listed the proper songs and there were 14.
“They just fell by the wayside of various projects from down the years.
“I’m going to record them. Some are quite old school.
“I was looking at the track listing and thinking, ‘Actually, fing hell, no I’d approach that song differently’.
“It’s been very interesting.”
Liam, 47, has said he is open to a reunion — claiming the band was offered £100million to tour last February — although Noel has dismissed the idea.
The group’s final studio album, Dig Out Your Soul, was released in 2008. Both Gallagher brothers continue to making music.
Noel, who performs with his band the High Flying Birds, said he could not leave the Oasis tracks alone.
Speaking on the Matt Morgan podcast, he explained: “The gift is not coming up with the chords. The gift I’ve been given is remembering it all. If I play a song once and I’m not ped and it connects, it’s in there forever. Obviously, I’ll forget about little things but years later I’ll be playing something and go, ‘Hang on, that’s that f***ing tune I had’. That’s the gift, not the songwriting. If they’re good enough they’ll come back.”
