The 2007 sessions were deemed a one-off which led to the Heaven and Hell side project, resulting in a new studio album in 2009 titled The Devil You Know. Though the second most recent line-up of the band to work together were Ronnie James Dio, Vinny Appice, Iommi, and Butler, for three new songs for a compilation in 2007, the original line-up was still considered the 'current' lineup at the time and had been since their reunion in 1997.
The band has undergone multiple lineup changes. The band was formed in 1968 by John 'Ozzy' Osbourne (vocals), Tony Iommi (lead guitar), Terence 'Geezer' Butler (bass guitar), and Bill Ward (drums). The discography of Black Sabbath, an English heavy metal band, includes 19 studio albums, eight live albums, 16 compilation albums, seven video albums, one extended play and 30 singles.
