To support the release of their third album, Let The Light Back In (DA Records), Luther Black and the Cold Hard Facts (well, one Cold Hard Fact) will play the Rockwood Music Hall in Manhattan on September 8. The music of this no-frills Americana band, based in Maplewood, has drawn comparisons to Texas troubadours like Townes Van Zandt, Guy Clark and Ray Wylie Hubbard.
