In 2006 the Ronnie James Dio-era Black Sabbath line-up recorded three new tracks , " The Devil Cried " , " Shadow of the Wind " , and " Ear in the Wall " for an upcoming greatest hits package entitled '' Black Sabbath : The Dio Years '' . Guitarist Tony Iommi said that the tracks were created because he felt there was nothing worth releasing in the vaults from the Dio-era studio recordings and so these new songs were written and recorded . The song " The Devil Cried " was released as a promotional single for the release . Initially Dio commented that after the recording of those songs , he expected to leave the band and return to Dio and that another " Sabbath album " was " the last thing on my mind " . Iommi commented that Heaven & Hell agreed on an album whilst the band was in Japan on their 2007 tour . The band started work on the album before and after the Metal Masters Tour in Dio and Iommi 's houses respectively . Each member submitted CDs of material for the project . Iommi described the work as " really good , pretty powerful "
