I absolutly love the Eagles "Desperado" Album. As concept albums go, this is one of the best. They draw on wild west history/myth of the Bill Doolin, Bill Dalton and the Wild Bunch gang to create a series of songs that take you into the midst of a crime wave from a hundred years ago while sounding like today. All the songs are good, but there are two major hits: Tequila Sunrise and Desperado.
