Scheff performed "Heart of Mine" several years later in 2007 for a theater-in-the-round setting at the Bluebird Cafe in Nashville.

The album, however, was rejected by Warner Bros. in 1993, and remained unreleased until 2008, when Rhino released it as Chicago XXXII: Stone of Sisyphus.

[citation needed] Scheff also enlisted Rascal Flatts vocalist and bassist Jay DeMarcus to serve as producer for the new album, which was released on March 21, 2006.

[3][4] In 2005, Scheff (credited as Jason Chefe)[5] appeared on the Pink Floyd tribute album Back Against the Wall, performing lead vocals and bass on the track "Run Like Hell", together with Dweezil Zappa (lead guitar), Tony Kaye (keyboard solo), Aynsley Dunbar (drums), Bob Kulick (electric guitar), and Billy Sherwood (keyboards).

In October of that year, Scheff left Chicago permanently, with Coffey initially as his successor before the latter was replaced by Canadian tenor vocalist Neil Donell and bassist Brett Simons in late 2018.

[citation needed] After leaving Chicago in 2016, Scheff participated as a judge for American Super Group.
