Halford and company got louder and faster after 1977's Sin After Sin -- but never better. It's the restraint and focus on this track that ignite its power. Every riff is calculated and deliberate, a far cry from the screaming and angry stuff heard throughout out much of the band's storied career.

Perhaps more than any other track, "Diamonds and Rust" showcased the songwriting quality and studio dexterity that, though later obscured by raw energy, made classics like "Breaking the Law" and "Painkiller" so powerful.
