It’s all about the voice, really. As Laura Jansen hits the angelic high notes of “Bells,” it’s obvious she possesses natural talent. This debut album combines her two EPs released in Holland, 2007’s Trauma and 2009’s Single Girls, with a newly-recorded version of Kings of Leon’s “Use Somebody” and a live version of “Single Girls” added as a bonus. Her songwriting is equally adventurous. “Single Girls” catalogs the things she’s done since breaking up with the lover she’s addressing in song. “Wicked World” adds extra sassy beats and vocal effects to make this Fiona Apple-like romp even more alluring. But it’s the purebred beauty and exquisite production of “Perfect,” “Come to Me” and the reggae “Soljah” that allow this natural soprano the room to become herself with outsized results. Her piano rendition of “Use Somebody” proves her great versatility. Her musical facility is not all that unexpected coming from a Berklee School of Music graduate, but the music’s incredible heart cannot be taught.
