The End (Black Sabbath EP) Sabbath had been planning a follow-up to "13", the album was ultimately scrapped. Guitarist Tony Iommi had written "a whole load of riffs" for the abandoned LP, but "Geezer (Butler) didn't particularly want to do another album" Iommi said of the bassist. Lead singer Ozzy Osbourne also voiced not wanting to record another album saying "If we were to do an album before the tour, it would take three or four years to complete the album." The EP was intended to be promoted with The End Tour, being only available for purchase at live dates. Cover art for the disc
