- Oasis' Noel and Liam Gallagher have a contentious relationship
- The hugely successful band broke up in 2009
(CNN)Noel and Liam Gallagher are burying the hatchet -- for now.
The brothers, who led the Britpop band Oasis to the top of the charts in the '90s with such albums as "What's the Story, Morning Glory" and "Be Here Now," have agreed to take part in a documentary about the band, the Guardian reported.
The film is being produced by Asif Kapadia and James Gay-Rees, who made the Amy Winehouse documentary "Amy."
At its height, Oasis was one of the most exciting -- and turbulent -- bands in rock 'n' roll. Guitarist Noel, five years older than Liam, wrote most of the songs, including "Live Forever," "Don't Look Back in Anger" and "Wonderwall" (the group's biggest U.S. hit); Liam sang them.
Both brothers lived up to the rock 'n' roll lifestyle of drink, drugs and endless parties. Their tempestuous relationship that made those of other rock siblings, such as Ray and Dave Davies or Don and Phil Everly, seem positively calm in comparison. Sometimes they bickered; sometimes one of them pouted. A lot happened in public.
They made excellent copy for the voracious British tabloids.
In 2009, Noel finally had enough.
"It's with some sadness and great relief to tell you that I quit Oasis tonight," he said on the band's website. "People will write and say what they like but I simply could not go on working with Liam a day longer."
In recent years, the two have lobbed insults at one another through the press while leading separate bands: Noel Gallagher's High Flying Birds and Liam's now-defunct Beady Eye.
Liam demanded a public apology in 2011 over one such quote, saying Noel had told a "lie" about his condition at a music festival.
But blood could be thicker than music. In a 1996 interview, Noel Gallagher defended the siblings' feuding.
"The one thing about this band is, we do have have arguments and fights, but it's not behind each other's backs," he said. "It's not like, waiting until the singer goes out of the room and then slagging him off. We're all up front with each other."
For a reunion, however, he's always had one key condition, he told Q magazine in January.
"If I was ever going to do it," he said, "it would only be for the money."
