Chicago XI

Chicago XI is the ninth studio album by the American rock band Chicago. It was released on September 12, 1977, through Columbia Records. It was both the last to feature guitarist and vocalist Terry Kath prior to his death in a gun accident just over four months later, and the last to be produced by longtime band associate James William Guercio. Chicago XI was a commercial and critical success for the band, reaching the top 10 in the US and garnering generally positive reviews. Three singles were released from the album—"Baby, What a Big Surprise", "Little One", and "Take Me Back to Chicago"—with the former reaching number four on the Billboard Hot 100. Chicago XI would become the band's last album to make the top 10 until Chicago 16 in 1982. The cover design for the album is called "Regional Map" on the group's official website.
