Formed in its namesake city in 1967, Chicago is the first American band ever to propel albums into Billboard®’s pop Top 40 for five consecutive decades, and is among the most successfully charting U.S.-grown acts of all time. Now, another page in the band’s history is revealed with the long-awaited release of Stone Of Sisyphus, the once shelved album that has attained legendary status among fans and critics alike. Recorded in 1993 and originally intended as Chicago XXII, the disc marked a return to the genre-transcending, adventurous fusion of sounds that defined the group’s 1970s-era heyday. Three tracks from it surfaced on Rhino’s 2003 Chicago box, but the album itself is previously unissued—now, this momentous release also features four incredibly rare bonus tracks.
