Hard rock thrives on juxtaposition. It's those sharp transitions between clean and dirty sound, heaviness and lightness, comfort and menace that makes the best rock songs sting as hard as they do. Sometimes the breaks are unexpected, and sometimes they're a release of tension at the climax of a long and ominous build. The punches might come in a flurry – or a series of slow, powerful blows. Sun & Flesh know how to do all of that.
