No one knows you quite like a sibling. That can result in a familiarity and a closeness that results in beautiful things. It can also result in sibling rivalries and infighting — as in the case of the Gallagher brothers in Oasis. Noel and Liam, the creative centers of the British band, aren’t exactly the closest of brothers these days. But back in their peak, they created some music magic that still resonates to this day — even if their relationship doesn’t. On “(What’s the Story) Morning Glory?,” Oasis took over the pop world with an album full of sonic, bombastic, pop-laden hits like “Wonderwall,” “Champagne Supernova” and “Don’t Look Back in Anger.” And in the process, they introduced a whole new generation to British power pop — and laid an uppercut to anyone who stood in their way — including each other.
