The Eagles formed in the early-1970s, blending folk, rock and country with crisp harmonies. The group went on to mega success until breaking up in 1980, but reunited through the intervening years for tours and new recordings.

Among the founding members of the Eagles was Don Henley, who, like Frey, found some success as a solo artist.
