Among the many gilded layers of “Everybody’s on the Run,” the opening blast from Noel Gallagher and his High Flying Birds’ self-titled debut, you’ll find a choir, an armada of strings and, we’re pretty sure, a few pockets of brass. They’re in there somewhere, but then again that’s the point: This is big, deep, wildly declarative rock’n’roll. It sounds like there’s something at stake. While we’re not taking sides or fanning any flames, if we were brother Liam right now hearing this music for the first time, we’d be staring at our shoes, kicking rocks, and muttering more than we normally do. No joke.
