Black Sabbath: The Dio Years is a 2007 compilation CD of material from recordings made during vocalist Ronnie James Dio's tenure in the band. The CD contains full album length, remastered tracks culled from all three studio albums: Heaven and Hell (1980), Mob Rules (1981), Dehumanizer (1992), and the live album Live Evil (1982). It also contains three new recorded songs: "The Devil Cried", "Shadow of the Wind", and "Ear in the Wall".
In an interview conducted by Martin Popoff, Tony Iommi revealed that in fact three tracks were recorded: "Shadow of the Wind" (a slow tune), "The Devil Cried" (a mid-tempo rocker) and "Ear in the Wall" (a fast song), therefore changing the original plan for two new songs to accommodate all three tracks in the compilation. "The Devil Cried" was released as a single on 13 March 2007.
On 23 February 2007, both Eddie Trunk and Sirius Satellite Radio unveiled the song "The Devil Cried" from the upcoming album. Rhino Records subsequently made the track available (for preview only) on 26 February 2007. On the week of 13 March 2007, it became available for download at all digital outlets.
After the recording was completed the members decided to tour under the moniker Heaven & Hell. Dio and Iommi decided that the working partnership they had achieved in recording the 3 new songs would not be wasted, so they recorded The Devil You Know.
Before the Heaven & Helltour of the UK in November 2007, a special edition release of The Dio Years was released on 5 November, Black Sabbath: The Dio Years Tour Edition, to commemorate the tour. This CD, only to be in print for a limited time, features four songs from the Live at Hammersmith Odeon limited edition live album recently released by Black Sabbath. The four songs, recorded live in 1981 during Black Sabbath's "Mob Rules Tour" are "Neon Knights", "The Mob Rules", "Children of the Grave", and "Voodoo".
