A sobered-up Mustaine returns with yet another lineup, this one featuring ex-Cacophony guitar virtuoso Marty Friedman and drummer Nick Menza, for what is easily Megadeth's strongest musical effort. As Metallica was then doing, Mustaine accentuates the progressive tendencies of his compositions, producing rhythmically complex, technically challenging thrash suites that he and Friedman burn through with impeccable execution and jaw-dropping skill. Thanks to Mustaine's focus on the music rather than his sometimes clumsy lyrics, Rust in Peace arguably holds up better than any other Megadeth release, even for listeners who think they've outgrown heavy metal. While the whole album is consistently impressive, the obvious highlight is the epic, Eastern-tinged "Hangar 18." ~ Steve Huey
