The Sometimes Boys' music is a Frankenstein's monster of folk, bluegrass, jazz, and what I can really only describe as showtune-style narratives. But this is not a monster that will want to make you run away in fear and terror (and I harbor almost-complete antipathy towards showtunes.)
The album seems to be a meditation on the cyclical nature of the seasons and life. To me, the thematic cohesiveness of the album elevates this ambitious music to a true artistry that isn't usually found among singers -- folk or otherwise. Every note on this album is intentional. Even if you're more fond of some of those notes than others, there's no faulting The Sometimes Boys for mediocrity.
This is one of the more adventurous albums I've heard all year.
