Bon Iver may be done for a little while, but between popping up on hip-hop albums big (Yeezus, My Beautiful Dark Twisted Fantasy, Watch The Throne) and small (P.O.S.’s We Don’t Even Live Here), playing with his band The Shouting Matches, and collaborating with The Blind Boys of Alabama, Justin Vernon hasn’t exactly been quiet. Nevertheless, the announcement of another album from Volcano Choir, a collaboration with post-rock band Collections of Colonies of Bees, was a bit of a surprise. Their 2009 album Unmap was a solid collection of abstractions with the occasional killer song (“Island, IS”, if you haven’t heard it, is still awesome), but it was a bit unstructured (and quite strange for my tastes). However, it seems to have been an important project for Vernon. Just look at the world of difference between For Emma and Bon Iver, Bon Iver: all the layered, more complex instrumentation. The odder, instrumentally complex, direction of Volcano Choir definitely had a hand in influencing that album’s left-turn from the dude-in-a-cabin scrappiness that defined his debut. On Repave, however, it’s Bon Iver that is influencing Volcano Choir.
