With their rich harmonies and brilliant fusion of country, bluegrass, and rock, the Eagles define the sound of Los Angeles in the '70s. From early breakthroughs, like the honey-drenched warmth of "Take It Easy" and the subdued heartbreak of "Tequila Sunrise," through the haunting gothic rush of "Hotel California" and into spirited reunion efforts like the sardonic "Get Over It," this sprawling set collects both the hits and essential deep tracks—like their thoughtful, Beach Boys-inflected take on Tom Waits' "Ol' 55."
