There's no art to noise-making; pulling music out of noise, on the other hand, is another matter entirely. "Broken," the new EP from Nine Inch Nails, is packed with brutal, abrasive sounds -- jagged shards of metal guitar, distortion-curdled vocals, drumbeats that punch and pummel. Yet beneath that tortured swirl of sound lies passion, a sure sense of song craft and an entrenched devotion to melody. That's how NIN maintains its tuneful intensity even in the face of ear-punishing aural aggression, from the slam-bang assault of "Last," through the dense, danceable roar of "Happiness in Slavery" to the clangorous crunch of "Physical" (one of two bonus tracks hidden at the end of the CD). Harder than Ministry, hookier than Nitzer Ebb, this EP is everything industrial music should be.
