Post-rock quartet Explosions in the Sky released their seventh studio album, “The Wilderness” early this April. As a fan and avid listener of their early material, I was skeptical that the group could deliver as engaging and original music as “Those Who Tell the Truth Shall Die, Those Who Tell the Truth Shall Live Forever” or ”The Earth Is Not a Cold Dead Place.” Their soundtrack material in the interim, such as “Friday Night Lights,” and also tracks off of “All of a Sudden I Miss Everyone,” begin to sound cookie-cutter in their almost melodrama, due only by the group’s early masterful sound.
