with a short film of the same name. According to the episode of Behind the Music featuring Styx, the early part of the supporting tour was a financial disaster, due to the fact that Styx had booked small, theater-sized venues for a more intimate experience, while later tour dates saw the group performing in large arenas to sold-out crowds. The album debuted at No. 10 on the Billboard 200 in its first week and sold over 1 million copies (although some sources say 2.5 million copies) and peaked at No. 3 on the US charts; however, it broke the streak of multi-platinum albums for Styx, and ushered in a more keyboard-oriented, theatrical direction. In an interview with the Chicago Tribune, James Young talked about the creative differences in the band, and what led to their breakup: "Dennis really wanted to do these soft, intimate love ballads, and that was against the grain for me and Tommy Shaw, so our differences got magnified, because Dennis was insisting on going outside the boundaries we lived with. He's an assertive and strongly opinionated guy." Despite the album's financial and chart success, after the Kilroy tour, the songs were not performed live by the band Styx (who fired DeYoung in 1999) in subsequent tours (with the exception of segments from "Mr. Roboto" and "Heavy Metal Poisoning" performed in the "Cyclo-medley"), until "Mr. Roboto" reappeared in full (in their encore) on May 30, 2018. DeYoung does perform the songs "Mr. Roboto" and "Don't Let It End" regularly during his solo tours. The James Young Group performed "Heavy Metal Poisoning" and "Double Life" as well on their tour in 1993. Music video Three of the four videos for the album—"Mr. Roboto", "Don't Let It End", and "Heavy Metal Poisoning"—were filmed at the same time and used footage from the minifilm. A fourth video, "Haven't We Been Here Before", was filmed a few months after the album was released; it did not interact with the album's story.
