Year Zero by Nine Inch Nails ($10) is a concept album about Armageddon that started out as experiment with noise, and the majority of the album reflects that. With more boundary-pushing compositions than anything Trent Reznor has done since The Downward Spiral, the album contains terrific, almost dance-like beats mixed with noisy guitars and other sonic disturbance, while the heavily-political lyrics paint a vivid picture of what the world could become if power and greed continue to overwhelm our world's leaders. Standout Tracks: "Survivalism," "Capitol G," "Meet Your Master."
