Oasis are officially back. The Brit rockers kicked off their highly-anticipated reunion tour July 4 with a dazzling set in in Cardiff, Wales that saw brothers Liam and Noel Gallagher play together on stage for the first time since 2009.

The pioneering Britpop band’s world tour — marking the first time famously feuding brothers Liam and Noel Gallagher have played together since 2009 — kicks off on Friday night in Cardiff, Wales, at Principality Stadium. Richard Ashcroft from the Verve is the opening act alongside Liverpool-based band Cast.

Liam Gallagher made a cheeky reference about high ticket prices for Oasis’ reunion tour during opening night in the U.K. Liam, 52, joked about the expensive tickets for the show onstage as he and his brother Noel Gallagher, 58, performed together for the first time in 16 years in Cardiff, Wales, on Friday, July 4.
