In the span of just a few years, The Decemberists' Colin Meloy has taken an unlikely path from brainy folk-pop obscurity to commanding frontman — the sort of confident singer who can fill open-air venues with his lone voice when he's not crafting ludicrously ambitious "folk operas" like 2009's The Hazards of Love. The Decemberists scaled back those ambitions on this year's lustrous-but-straightforward The King Is Dead. But make no mistake: Songs this infectious aren't crafted without a healthy dollop of ambition — and an even greater application of craft and skill.
