"Oasis played the same music right the way through."
Shall we compare and contrast Rock N Roll Star, Supersonic, Cigarettes and Alcohol, et cetera, with The Shock of the Lightning?
Oasis became incredibly different once the Definitely Maybe and WTSMG era ended. That put them into the limelight and Be Here Now was the band, now filthy rich, on silly amounts of cocaine, in the transition period. And it all went downhill from there.
