Diego Rivera was a split release between Ebullition and Sovereignty. It was the last release that Manumission would ever do.

It features two studio tracks on side A, and four live tracks that were recorded on KXLU Radio on side B. Sean Sellers, who also played drums for Downcast, Jara, Not For The Lack of Trying, and later Good Riddance, played drums for Manumission on this recording.
