But as time goes by, this connection slowly wears off - or at least, this is what Andy Bell, the band's guitarist, tells Young Post.
Beady Eye consist of lead singer Liam Gallagher, guitarists Gem Archer and Andy Bell, and drummer Chris Sharrock, who were all members of Oasis. This year, bass player Jay Mehler, formerly of Kasabian, joined.
The band's latest work is their new 15-track rock album, BE, released on June 10.
"We definitely have changed from the first one to the second one," Bell says, comparing BE with the band's debut album, Different Gear, Still Speeding, released in 2011. "The first one we made directly after the band split, and there were a lot of sounds we had written during the Oasis period."
The friendly-sounding guitarist says BE is different because it's the first time the band has finally had time to sit down and write new material. It was also produced by an American producer, Dave Sitek, with whom the band has not worked before.
"In the new album, we've gone into a little bit more ambient sound," Bell says.
But if the band claim they have cut off all connections with Oasis, it'd probably be a lie, as the three members who had taken part in the songwriting for the latest album are all from Oasis.
The members, for example, still keep their rituals, in which they have a minute or two of silence before starting a show. Bell says they are still the same people, so there is no point in acting differently. "It's the same players, but writing our own materials," he says.
"Oasis was run very well by Noel Gallagher. And then, this is what we get up to when Noel is not around. So it's like me, Liam and Gem writing our own music, directing how it sounds."
The band has already earmarked a few places for their upcoming tours, including Scotland, Spain and Japan.
Hong Kong and the Far East, Bell says, will be on the band's mind as they would love to come here and introduce true rock music to young people.
Bell gets excited when he sees people who weren't even born when Oasis started, now standing in the front row at Beady Eye's concerts.
"They obviously want to hear some good rock music, and I think that this kind of thing is timeless," he says.
