Grindcore lives. The legions of the metal underground will lend ears and lift horns every time the kids do it right: cram as much full-on savagery into as few seconds as possible. Atlanta trio Dead In the Dirt get there again, as they have gotten there before. Their upcoming The Blind Hole (due August 6 via the ever more “-core” friendly Southern Lord) offers us a glorious grind ratio: 22 songs in under 24 minutes. Press play on “The Blaring Eye” now — experience a tightly constructed blast of warp-speed riffage, shrieks, and d-beat drum battery that could conclude before you reach the end of this sentence.
