Styx  is an American rock band from Chicago that formed in 1972 and became famous for its albums released in the late 1970s and early 1980s. They are best known for melding hard rock guitar balanced with acoustic guitar, synthesizers mixed with acoustic piano, upbeat tracks with power ballads, and incorporating elements of international musical theatre. The band established itself with a progressive rock sound in the 1970s, and began to incorporate pop rock and soft rock elements in the 1980s. Styx is best known for the hit songs "Lady",

Dennis DeYoung and Tommy Shaw released a string of solo albums, beginning with DeYoung's Desert Moon and Shaw's Girls with Guns in 1984. Both Shaw and DeYoung generated a moderate amount of interest with their first solo albums. DeYoung scored a Top 10 hit with the title track, "Desert Moon", which was also heavily featured on MTV. Shaw also cracked the Top Forty with "Girls with Guns" and he made a cameo appearance on the NBC television series Miami Vice. DeYoung's follow up single "Don't Wait for Heroes" also featured a video that was heavily featured on MTV, but it failed to generate significant radio airplay, only peaking at No. 83. During the filming of the video, DeYoung injured his back, causing him to back out of opening a North American concert tour for Huey Lewis and the News. Shaw, however, did tour in the fall of 1984 as an opening act for the Kinks.  Shaw's 1985 album What If and DeYoung's 1986 album Back to the World also charted, along with singles from film soundtracks. Shaw's "What If (Remo's Theme)" from Remo Williams: The Adventure Begins entered the Billboard Hot 100, while DeYoung's "This Is the Time" from The Karate Kid, Part II soundtrack was featured for a short while on MTV. The first single from DeYoung's Back to the World album, "Call Me", peaked at No. 6 on the Adult Contemporary chart and was a modest pop hit, peaking at No. 54 on the Billboard Hot 100.  However, by the late 1980s, both Styx members' solo careers gradually simmered down to a modest but loyal fan base. Neither Shaw's Ambition (1987) nor DeYoung's Boomchild (1989) achieved nearly the same levels of earlier albums, although Shaw's cover of Jim Peterik's "Ever Since the World Began" charted briefly. Shaw also recorded sessions with Peterik's group, Survivor, on 1986's When Seconds Count, and Shaw's solo band opened the majority of the US shows for Rush's 1987-88 Hold Your Fire Tour.  Meanwhile, James Young recorded his own solo albums: City Slicker (1985 with Jan Hammer) and Out on a Day Pass (1988), both attracting only minimal attention. In 1995 James Young partnered with other Chicago musicians and released an album under name James Young Group titled "Raised by Wolves".  In 1989, Tommy Shaw formed Damn Yankees with Ted Nugent, Jack Blades and Michael Cartellone. Meanwhile, the remaining members of Styx made plans for a comeback in the new decade.
