Volcano Choir: Unmap

On Bon Iver’s acclaimed 2008 debut For Emma, Forever Ago, Justin Vernon subverted the usual formula for a confessional singer-songwriter record, conveying the emotional core of his songs via the sound of his lyrics—which rang down in a blurry, inarticulate choir of overdubbed vocals—rather than their literal meaning. With Volcano Choir, his years-in-the-making collaboration with Milwaukee post-rock instrumental band Collections Of Colonies Of Bees, Vernon embraces full-blown abstraction on the willfully difficult Unmap. Fans of For Emma might think he’s lost the songs in the process—only the bubbling “Island, IS” is satisfying in a traditional, pop-friendly sense. The rest of the record consists of slow-building, noodly, frequently pretty sketches like “Still,” where Vernon’s vocals are treated like another instrument floating in the ether.
