The artworks are signed by Ozzy and named after his songs and albums: Technical Ecstasy, Electric Funeral, Blizzard of Ozz, Tattooed Dancer and Paranoid. Ozzy painted acrylic base coats onto the canvases and then the apes at the sanctuary added their own brushstrokes.

"Last Rites" also includes reflections on Osbourne's relationship with his wife Sharon, as well as his encounters with fellow rockers Slash, Bon Scott, John Bonham, and Keith Moon, and "the harrowing final moments he spent with Motörhead's Lemmy Kilmister," according to the press release.
