Even with a fluid lineup, country rockers the Eagles always maintained continuity thanks to the sunny harmonies and songwriting smarts of core members Don Henley and the late Glenn Frey. In fact, those co-founders are the only two players who performed on every album and tour from their 1972 debut through their 2016 swansong.

Along the way, the group’s arsenal of hits included “Take It Easy,” “Already Gone,” “Best of My Love,” and “One of These Nights,” though the Eagles’ true apex was their Hotel California album in 1976. Not only did it yield the smash title track, “Life in the Fast Lane” and “New Kid in Town,” but it eventually sold more than 20 million copies around the world.

Though squabbles kept the band apart through much of the ’80s, 1994’s Hell Freezes Over reunion album and tour found the Eagles topping the charts and banking at the ticket window once again after a 14-year hiatus. And the juggernaut kept on rolling right up until Frey’s sudden death, which was commemorated by the surviving members’ final performance at the 58th Annual Grammy Awards.
