Judas Priest

When the disembodied guitar solo that shoots "Sinner" to the stratosphere comes drifting in, you can actually pinpoint the exact moment Slayer's Kerry King and Jeff Hanneman and Obituary's Allen West were all born. "Dissident Aggressor" is another one on here that gives an almost textbook illustration of Judas Priest's incalculable effect on all metal that came in the wake of Sin After Sin. Rob Halford performs a call-and-response routine with himself. Meanwhile, "Diamonds and Rust" marks the first time in recorded history a Joan Baez song didn't sound annoying.
