Volcano Choir just released the album trailer for Repave, the long-awaited follow-up to the Justin Vernon-led indie group’s 2009 effort Unmap.

Repave builds exponentially from the musical relationship built on their 2009 debut, Unmap, and finds the band operating as a fully-realized unit, crafting their new album together over the past three years at the Fall Creek, Wisconsin studio, April Base.

The new album comes out September 3.
