Heaven and Hell was formed to record three new songs for the 2007 Black Sabbath collection, The Dio Years. Tony Iommi, Ronnie James Dio and Geezer Butler then enlisted drummer Vinny Appice to stand in for Bill Ward and set out on a tour to promote the (then) upcoming album. A recording from the tour, Live From Radio City Music Hall, was released in August 2007. The set chronicles the band's Dio years, including songs from each album recorded with the singer and highlighted by "Die Young," "Neon Knights," "Sign of the Southern Cross" and the band's paced, menacing play throughout. Further collaborations and reunions were not announced, but not ruled out by Iommi and Dio, either.
