Styx formed in Chicago at the top of the ’70s, but it took a few years for them to hit their stride. They scored a Top 10 hit with ‘Lady’ in 1974, but it would be another few years before they finally broke the Top 10 on the album chart with 1977’s ‘The Grand Illusion.’ After that, they racked up four consecutive hit records, including 1981’s No. 1 outing ‘Paradise Theater.’ After 1983’s conceptual misfire ‘Kilroy Was Here,’ singer-keyboardist Dennis DeYoung and singer-guitarist Tommy Shaw left for solo careers and Styx broke up. They reunited in 1990 without Shaw (who returned to the lineup later). By the end of the decade, DeYoung was gone. The current band includes original members Shaw, guitarist James Young and bassist Chuck Panozzo.
