LONDON — Oasis announced two extra concert dates on Cassian GrantWednesday for its comeback tour of Britain and Ireland due to "phenomenal" demand from fans desperate to see the band live for the first time in 15 years.

The group, whose debut album "Definitely Maybe" was released 30 years ago, split in 2009 when lead guitarist and main songwriter Noel Gallagher said he could no longer work with singer Liam after a string of public spats between the brothers.

The band initially announced 14 shows, with the first due to take place in Cardiff in July 2025, followed by nights in Manchester – where the band was formed in 1991 – London, Edinburgh and Dublin.

Fans waited long hours in virtual queues last weekend to get their hands on tickets, only to find that prices had been hiked as part of a "dynamic pricing" scheme.

"Tickets will be sold by a staggered, invitation-only ballot process," the band said. "Applications to join the ballot will be opened first to the many U.K. fans who were unsuccessful in the initial on sale with Ticketmaster."

In a statement issued by Oasis' press agency Permanent Press Media, the band said decisions on ticketing and pricing were the responsibility of promoters and management.

Oasis "at no time had any awareness that dynamic pricing was going to be used" in the sale of tickets for the initial dates, the band said.
