There’s something very refreshing about the way Seattle folk-pop troupe The Head and the Heart ascended from nowhere to national prominence over the past two years. They weren’t blog or Pitchfork darlings (in fact, that old digital rag panned the band’s debut), and weren’t lucky enough to have a song placed in an Apple ad. And yet THAH independently sold 10,000 copies of their debut before signing with indie heavyweight Sub Pop and occupying enviable opening slots for Vampire Weekend, Dr. Dog and (wait for it) Dave Matthews. You could say the six-piece was plucked from obscurity, sure, but only in the old-fashioned sense: After THAH won over most of Seattle with what I’m told is a fantastic live show, support from local radio and record stores drove the word-of-mouth that catapulted them into the forefront of mainstream indie and beyond. Whether the band’s success can also be attributed to the rise of The Avett Brothers or Mumford & Sons is up for debate (the three share a certain nu-Americana quality), but one thing’s certain: Two sold-out nights at Cannery means we’ve been seduced, too.
