This box set perfectly captures the Eagles’ transformation into classic-rock icons. The first disc covers their early country-rock days, when the Hotel California was more of a roadhouse. Next up: two discs from their mid-'70s peak, split between sweet ballads like the yearning "I Can't Tell You Why" and swaggering rockers like the edgy "Life In the Fast Lane." Finally, a live set recorded on the last day of the '90s, which is as tight and precise as their classic-era albums.
