Chicago XI is the ninth studio album (eleventh overall) by the American band Chicago, released in 1977. As the successor to Chicago X, the album marked the end of an era for Chicago in more ways than one. This would be the last Chicago album to feature guitarist and founding member Terry Kath prior to his death, and the last Chicago album to be produced by James William Guercio.
