The baroque Londoners double down with an entire mountain range of towering pop choruses. And as band introductions go, this 25-track behemoth—featuring Bastille’s debut record, additional original tracks and covers like the joyous splicing of Snap! and Corona that is “Of the Night”—is pretty undeniable. From the giddy chanting of “Pompeii” onwards, frontman Dan Smith displays a dazzling ear for melody that’s strong enough to match the mythic grandeur of his lyrics.
