Cyclorama is the fourteenth studio album by Styx, released in 2003. This was the first studio album with Lawrence Gowan, following the departure of group co-founder Dennis DeYoung in 1999. It was also the latter of two albums to feature Glen Burtnik, and the only album released by the Lawrence Gowan/Tommy Shaw/James "JY" Young/Glen Burtnik/Chuck Panozzo/Todd Sucherman lineup, and as such the only original Styx album to feature four different singer-songwriters as opposed to the usual three. The album peaked significantly higher on the Billboard album charts than Styx's previous release, Brave New World (1999), ending up 48 slots higher at No. 127, but paled in comparison to previous 1970s and 1980s releases on A&M Records.

Styx is an American rock band formed in Chicago, Illinois, in 1972. They are known for blending melodic hard rock guitar with acoustic guitar, synthesizers mixed with acoustic piano, upbeat tracks with power ballads, and incorporating elements of international musical theatre. The band established themselves with a progressive rock sound during the 1970s, and began to incorporate pop rock and soft rock elements in the 1980s.
