The album includes three new studio songs along with the live recordings, taken during 2008 and 2009. The new tracks include "Undefeated," composed by Joe Elliott, who described it as "a big, epic, rock anthem...kind of 'We Will Rock You' with guitars," as well as "It's All About Believin'," by Phil Collen and "Kings of the World," by Rick Savage and described by Elliott as having "a very Queen-type vocal thing," The complete track listing was announced on 7 April 2011.
During its first week on sale, the album sold approximately 20,000 copies in the United States, charting at number sixteen on the Billboard 200.
Allmusic gave Mirror Ball – Live & More a rating of three and a half out of five stars, noting the change in Joe Elliott's voice, "from a metallic screech into a coarse croon," and saying that the album was "far better than most fans will expect it to be."
