Chicago XXXII: Stone of Sisyphus

Chicago XXXII: Stone of Sisyphus is the twenty-first studio album, and thirty-second overall, by Chicago. Often referred to as their "lost" album, it was recorded in 1993 and originally intended to be released as Stone of Sisyphus on March 22, 1994, as their eighteenth studio album and twenty-second total album. However, the album was unexpectedly and controversially rejected by the record company, which reportedly contributed to Chicago's later decision to leave their services entirely. Even after the band eventually acquired rights over their catalog, the album remained unreleased until June 17, 2008, after a delay of fourteen years and ten more albums.
