Chicago XXX

Chicago XXX is the twentieth studio album, and thirtieth album overall, by the American band Chicago, released on March 21, 2006. It was Chicago's first album of entirely new material since 1991's Twenty 1.

Background
The album was recorded in Nashville, Tennessee with horn sessions in Los Angeles, California over the summer of 2005. Production duties were handled by Jay DeMarcus of the country group Rascal Flatts, who came to the project through a friendship with Chicago's bassist-singer Jason Scheff. DeMarcus used several session players for the album.

Chicago XXX peaked at number 41 in the US during a brief chart stay, spawning minor hits "Feel" and "Love Will Come Back." This would be the last studio recording with long-time vocalist and keyboardist Bill Champlin, as he departed Chicago in August 2009.
