Volcano Choir is an assembly of Wisconsinites Jon Mueller, Chris Rosenau, Jim Schoenecker, Daniel Spack, Justin Vernon, and Thomas Wincek. You might find these old friends also frequenting records and stages under different monikers, Collections of Colonies of Bees and Bon Iver. The collaboration predates the meteoric rise of Justin Vernon's Bon Iver project, with original songwriting dating back to the summer of 2005.
