NEW YORK (Billboard) - Former Oasis guitarist and vocalist Liam Gallagher says that he and the other members of the band -- aside from his brother Noel -- are writing songs and will perform as a new group.

"We're sort of doing things at the moment," he said during an Italian radio interview to promote his Pretty Green clothing line. "Not Oasis, Oasis is done. Everyone except for Noel."

Liam Gallagher founded the band in 1991 with Paul Arthurs, Paul McGuigan and Tony McCaroll. Noel joined shortly thereafter and took over as Oasis' lead songwriter. The Gallagher brothers were the longest-standing members of the band; the rest of the current lineup includes guitarist/keyboardist Colin Archer, bassist Andy Bell and drummer Chris Sharrock.

Liam quit the band in late August, shortly after the last-minute cancellation of the group's scheduled performance at the Rock En Seine festival in Paris.

"It's with some sadness and great relief to tell you that I quit Oasis tonight," Gallagher wrote 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."

During a later interview with the London Times, Liam said, "It's a shame, but that's life. We had a good run at it. The thing about Oasis is, no one ... we ended Oasis. No one ended it for us. Which was pretty, kind of ... cool. I'm thinking of what the next step is musically, which is all my mind's on."

He added: "I'll be doing music to the day I die. People will be able to buy his (Noel's) records. People will be able to buy our records. So everyone's happy."

Oasis' most recent album, "Dig Out Your Soul," peaked at No. 5 on the Billboard 200 last October.
