Oasis gossip comes fairly cheap, but the latest news from the Brit-pop powerhouse may actually cost the band their very existence. Noel Gallagher, guitarist and older brother of vocalist Liam Gallagher, announced Friday on his blog he had quit the band for good this time.

“People will write and say what they like, but I simply could not go on working with Liam a day longer,” Noel wrote on oasisnet.com.

The post came after an altercation between Noel and Liam at the Paris music festival Rock en Seine. The two were so worked up they bowed out of their headlining set moments before they were scheduled to take the stage, disappointing fans even to the point of tears, according to drummer Chris Tomson’s statement to NME.

Vampire Weekend played the slot directly before Oasis and walked off stage into the midst of the confrontation between the brothers.

“It’s a story for Oasis to tell,” keyboardist Rostam Batmanglij told NME at the Leeds Festival the next day. “We’d just come offstage. It was weird – you feel kind of good [having played], your mind is not on other people’s problems. It was a strange time.”

Of course, Oasis have turned this trick dozens of times, and very publicly at that.

Both brothers have stormed off the stage mid-set, dropped off tours and slandered the other via interviews, on stage or most recently through Twitter. But entertainment media around the world seem to be taking this split more seriously and have already begun questioning the future of the 18-year-old band.

NME reported that while Liam said he has no intention of pursuing a solo career, he has said he would carry on with Oasis should Noel ever leave beacuse he was the one who started the band in the first place. On the other hand, Noel said he has written a number of songs that don’t belong to Oasis and a solo record is a possibility.

The Mirror UK reported both the Gallagher’s mom and the man responsible for discovering them, Creation Records’ boss Alan McGee, believe this is all just a spat and they will reunite in the end.

Noel’s wife, Natalie Appleton (former member of All Saints) told NME “Oasis will die before they split up…They’re going to go on forever until they are old men.”

The Guardian UK’s John Harris wrote a column on Aug. 25 – three days before Noel called it quits – titled “Oasis: Is it really over?” detailing the rapidly expanding divide between the brothers over the last year. The column even mused the Milan gig on Aug. 30 could be the band’s last.

Looks like they couldn’t even hold out that long.
