Jeff Bass is one half of the rap production duo Bass Brothers. Bass Brothers is the professional name for the team of Mark and Jeff Bass, the Detroit producers responsible for grooming rapper Eminem in his early days and collaborating on much of his subsequent music. Before that they worked with George Clinton. Tracks from those sessions ended up on the P-Funk All Stars album Dope Dogs. The "Dynamic-Duo" are documented to be one of the highest paid producers in the history of Hip-Hop.
