Heaven and Hell September 7, 2007

Original Black Sabbath members Tony Iommi, Geezer Butler and Bill Ward are reuniting with vocalist Ronnie James Dio, who replaced Ozzy Osbourne in the band in 1979, under the moniker Heaven and Hell. The new group, named after the first post-Osbourne Sabbath album, will be drawing from the band's back catalogue, with some new material planned as well. Machine Head consists of vocalist/guitarist Robb Flynn, guitarist Logan Mader, bassist Adam Duce and drummer Chris Kontos. The group's blend of hardcore and metal surpasses other bands with a similar style because of catchier riffs and better dynamics. Formed in 1983, Megadeth became one of the leading metal bands of the '80s and '90s.
