Good Bread Alley: Good Bread Alley is the third studio album of Carl Hancock Rux.

The cd tackles religion, sexual politics, war and media overload, in the tradition of Marvin Gaye and Donny Hathaway, employing supersaturated, open-ended soul music with bluesy vamps, touches of minimalism, and slide-guitar licks providing a rich backdrop for Rux's sardonic baritone, achieving a pop-gospel synthesis.
