British rock band Oasis reunited in Cardiff on Friday as the Gallagher brothers put more than 16 years of acrimony behind them to deliver a hit-packed set that took thousands of fans back to the optimism and swagger of the 1990s. The Manchester band defined the "Britpop" revival of guitar music, before tensions between Noel Gallagher, the band's main songwriter, and his younger brother, lead singer Liam, led to its split. The group walked onto the stage in the 74,500-capacity Principality Stadium and launched into "Hello," sounding as tight as at the height of their fame.
